The force of gravity is also known as
Answer:
Gravitation
Explanation:
Gravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. ... On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth's mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects.
The force of gravity is also known as acceleration due to gravity g
The force of gravity which can also be expressed as gravitational force of attraction is also known as acceleration due to gravity
In the early science, scientist assume that the earth attracts all object to itself with a force called gravitational force of attraction. The S.I unit of the magnitude of this force, was initially expressed in Newton.
This gravitational force of attraction was latter addressed to be acceleration due to gravity in which the S.I unit of its magnitude is expressed in meter per squared meter.
Therefore, the force of gravity is also known as acceleration due to gravity

c. What did you notice with the acceleration values obtained by the different items? What do you think caused the variations in these values?
Explanation:
The given table gives the acceleration of an object for the different items at 50 N force.
Force acting on an object is given by :
[tex]F=ma[/tex]
As, [tex]a=\dfrac{v-u}{t}[/tex]
where u and v are initial and final velocities
It can be noticed that, as the mass of the object increases and final velocity decreases, the value of acceleration also decreases. It is maximum when the mass is least and the final velocity is most. As mass and velocity is changing, it will cause the change in variations of the value of a.
Variation in the values of acceleration occurs due to the different in the final velocity of different items.
The acceleration values obtained by the different items varies from one another because of different mass as well as final velocity. Acceleration depends on both mass of an object as well as velocity. We know that acceleration is the time rate of change of velocity.
So if the change occur in velocity we also experience change in the acceleration of that object so we can conclude that variation in the values of acceleration occurs due to the different in the final velocity of different items.

A person weighs 784 N on Earth.
On the moon, Gmoon = 1.60 m/s2.
How much would this person
weigh on the moon?
F = [?]N
Hint: Use the gravity of the moon in F = ma.
Answer:
W'=125.44 N
Explanation:
The weight of a person on the surface of Earth is 784 N
Weight is given by :
W = mg
m is mass of the person and g is acceleration due to gravity on the surface of Earth (10 m/s²)
[tex]m=\dfrac{W}{g}\\\\m=\dfrac{784}{10}\\\\m=78.4\ kg[/tex]
The acceleration due to gravity on the surface of Moon, g' = 1.6 m/s²
Weight of the person on the moon is :
W'=mg'
[tex]W'=78.4\ kg\times 1.6\ m/s^2\\\\W'=125.44\ N[/tex]
Hence, the person would weigh 125.44 N on the Moon.
Answer:
129 N
Explanation:
The answer you're looking for is 129 N
Weight on Earth, divide by Earth's gravity (≈9.80), multiplied by the gravity of the Moon (≈1.60).

Of the 10 Amendments in the Bill of Rights discussed this week, which one do you believe is most important to our freedom as Americans? Why?
Explanation:
creating law(representers of citizens by hearing the vote of a citizen) doing the law (different Ministers will form different offices to make the law) courts
Answer:
By the time the Constitutional Convention met in Philadelphia in 1787, it had become clear to many American leaders that a more powerful federal government was necessary in order to effectively deal with the challenges facing the young nation.
Under the Articles of Confederation, the central government had neither the power to raise taxes nor the authority to regulate interstate commerce. Additionally, there was no established mechanism through which states could adjudicate conflicts. Many of the delegates to the Constitutional Convention understood that the Articles of Confederation would need to be supplanted entirely, not merely revised.
To this end, the delegates spent months debating and shaping the scope and contours of a new and more powerful federal government.
The result of the Constitutional Convention was the United States Constitution. The Constitution created a federal government consisting of three separate branches in order to impose checks and balances on the powers of each branch.
The executive branch would be headed by a president, who would be elected.
The legislative branch would be composed of an upper house, the Senate, and a lower house—the House of Representatives. Representation in the House would be based on population—including counting enslaved men and women at the proportion of three to five for the purposes of representation and taxation. Each state would elect two representatives to the Senate.
The judicial branch would consist of a Supreme Court and lower courts to interpret and apply the law.
Not everyone believed the new Constitution was a good idea. A number of individuals who had played important roles in the Revolution, like Samuel Adams and John Hancock, worried that a powerful federal government would inevitably become tyrannical and that the new Constitution would be merely replacing British tyranny with a homegrown variety. They worried that the president would usurp king-like powers and encroach upon the individual rights and freedoms of citizens.
In order for the Constitution to enter into force, it would have to be ratified by at least nine states, but several states threatened to refuse to ratify the document unless it included strong guarantees of individual rights and liberties. To this end, the delegates, led by Virginian James Madison set to work on drafting a list of checks on federal power that would ensure the full exercise of individual liberty.
The Bill of Rights consists of 10 amendments that explicitly guarantee certain rights and protections to US citizens by limiting the power of the federal government.
The First Amendment prevents the government from interfering with the freedoms of speech, peaceable assembly, and exercise of religion.
The Second Amendment declares that properly constituted militias are a safeguard of liberty and that the right to bear arms will be protected.
The Third Amendment restricts the quartering of soldiers in private homes—an extremely contentious issue that had led the colonists to war with Great Britain.
The Fourth Amendment protects citizens against unreasonable searches and seizures of private property.
The Fifth, Sixth, Seventh, and Eighth Amendments establish a variety of guarantees relating to legal proceedings and criminal justice, including the right to a trial by jury; protection against self-incrimination and double jeopardy, being tried twice for the same offense; the right to due process; prohibition of cruel and unusual punishment; and the right to face one’s accuser, obtain legal counsel, and be informed of all criminal charges.
The Ninth Amendment acknowledges that the other eight amendments are not an exhaustive list of all of the rights and protections to which citizens are guaranteed, and the Tenth Amendment declares that any powers not explicitly delegated to the federal government in the Constitution are to be left to the states. This reinforced the principle of federalism, or separation of powers, by ensuring that the federal government could not usurp rights and powers that were not explicitly authorized in the Constitution.
The Bill of Rights has proven to be one of the most influential documents in contemporary history, codifying the theory of natural rights, which holds that humans are granted certain freedoms and liberties by God, and that the state should not have the power to usurp or otherwise infringe upon those rights. This was a major departure from previous theories of individual rights, which were granted to citizens by the state or monarch. The Bill of Rights has influenced countless political leaders around the globe since their authorization into force in the United States.

A cyclist is traveling 10 m/s with an acceleration of 6 m/s2. How fast is the cyclist traveling at the end of 20 seconds
Answer:
The cyclist is traveling at 130 m/s
Explanation:
Constant Acceleration Motion
It's a type of motion in which the velocity of an object changes by an equal amount in every equal period of time.
Being a the constant acceleration, vo the initial speed, vf the final speed, and t the time, the following relation applies:
[tex]v_f=v_o+at[/tex]
The cyclist initially travels at 10 /s and it's accelerating at a=6m/s^2. We need to know the new speed when t= 20 seconds have passed.
Apply the above equation:
[tex]v_f=10+6\cdot 20[/tex]
[tex]v_f=10+120[/tex]
[tex]v_f=130\ m/s[/tex]
The cyclist is traveling at 130 m/s

A 120 kg box is on the verge of slipping down an inclined plane with an angle of inclination of 47º. What is the coefficient of static friction between the box and the plane?
Given :
A 120 kg box is on the verge of slipping down an inclined plane with an angle of inclination of 47º.
To Find :
The coefficient of static friction between the box and the plane.
Solution :
Vertical component of force :
[tex]mg\ sin\ \theta = 120\times 10 \times sin\ 47^\circ{}=877.62 \ N[/tex]
Horizontal component of force(Normal reaction) :
[tex]mg\ cos\ \theta = 120\times 10 \times cos\ 47^\circ{}=818.40 \ N[/tex]
Since, box is on the verge of slipping :
[tex]mg\ sin\ \theta= \mu(mg \ cos\ \theta)\\\\\mu = tan \ \theta\\\\\mu = tan\ 47^o\\\\\mu = 1.07[/tex]
Therefore, the coefficient of static friction between the box and the plane is 1.07.
Hence, this is the required solution.

In order to solve this problem, we must make a free body diagram and include the respective forces acting on the body. Similarly, deduce the respective equations according to the conditions of the problem and the directions of the forces.
Attached is an image with the respective forces:
A summation of forces on the Y-axis is performed equal to zero, in order to determine the normal force N. this summation is equal to zero since there is no movement on the Y-axis.
Since the body moves at a constant speed, there is no acceleration so the sum of forces on the X-axis must be equal to zero.
The frictional force is defined as the product of the coefficient of friction by the normal force. In this way, we can calculate the coefficient of friction.
The process of solving this problem can be seen in the attached image.
