Newton's Laws
Bode made a rocket using an empty plastic bottle and fins made out of cardboard. After partially filling the bottle with water, he
pumps air into the bottle using a pump attached to the rocket with plastic tubes. When the pressure in the bottle becomes high
enough the water gushes out and launches the rocket into the air, as shown in the diagram below.

How does the force that causes the water to leave the rocket compare to the force that causes the rocket to launch?
They are ental
Answers
Answer:They are equal and act in opposite directions.
Explanation:Newton's third law of motion states that for every action there is an equal and opposite reaction. In the case of Bode's rocket, the pressurized air in the bottle forces the water to gush downward out of the bottle, causing the rocket to launch upward into the air. The force of the water gushing downward is equal to the upward force on the rocket. So, the two forces are equal and act in opposite directions.
The force that causes the water to leave the rocket compared to the force that causes the force to launch is equal but opposite in direction.
What is Newton's law?There is a threes law given by the scientist newton in relation to the motion. The first law tells that if a body is in stop mode, then they become in motion once an external force is applied to them. The second law tells that force is equal to the product of mass and acceleration of the body. The third law tells that if you apply force to an object, then the object also applies force in reaction.
According to Newton's third law, the rocket applies force to the water, then the water also exerts a force on the rocket.
In the instance of Bode's rocket, the bottle's pressured air causes the water to pour out of the bottle downward, which causes the rocket to shoot upward into the air. The upward force on the rocket is equivalent to the force of the water pouring down. Therefore, the two forces are equivalent and exert opposing forces.

A spring is stretched downward by a certain length and, as a result, exerts a
force in the upward direction. What happens to the force exerted by the
spring if the length by which it is stretched is reduced by half?
O A. The force exerted by the spring is reduced by half.
B. The force exerted by the spring is doubled.
O C. The force exerted by the spring reduced by one quarter.
O D. The force exerted by the spring remains unchanged.
Answers
Answer:
A
Explanation:
Hooke's law! F(spring)=-kx
There's no tricky square law here. The spring constant doesn't change, only x (distance stretched) changes. Therefore, if distance is halved, Force will be halved.

What is the speed of a 180 g ball if its kinetic energy is 100 J?
Answers
Answer:
Velocity, V = 33.33 m/s
Explanation:
Given the following data;
Mass = 180grams to kilograms = 180/1000 = 0.18 kg
Kinetic energy = 100J
To find the speed;
Kinetic energy can be defined as an energy possessed by an object or body due to its motion.
Mathematically, kinetic energy is given by the formula;
[tex] K.E = \frac{1}{2}MV^{2}[/tex]
Where;
K.E represents kinetic energy measured in Joules.
M represents mass measured in kilograms.
V represents velocity measured in metres per seconds square.
Substituting into the equation, we have;
100 = ½*0.18*V²
Cross-multiplying, we have;
200 = 0.18*V²
V² = 200/0.18
V² = 1111.11
Taking the square root of both sides, we have;
Velocity, V = 33.33 m/s

Burning fuel in a rocket causes a push that propels the rocket forward from the front. The exhaust gas is pushed rearward in an equal and opposite direction as a result.
What is Newton’s law?The three fundamental laws of classical mechanics known as Newton's laws of motion describe how an object's motion and the forces acting on it interact.
The following is a paraphrasing of these laws: Unless a force acts upon a body, it remains at rest or in continual straight-line motion.
The creation of thrust by a rocket engine can be understood via Newton's third law. In a rocket engine, a fuel and an oxidizer are burned to produce hot exhaust gas.
The hot exhaust gas from the rocket accelerates to the back of the rocket after passing through the nozzle.
Thus, this way, Newton’s law of action–reaction best be applied to rocket movement.

In physics, momentum is the product of mass and velocity. The greater the product of this equation, the greater the momentum. In science, there are two types of momentum: angular and linear, which concern different types of moving objects. However, that is not where the definition stops. The word momentum is also used as part of everyday speech, and is one of the very few physics concept whose metaphorical definition is the same as its actual one.

In the example below, the net force would be 900 Newtons (450 + 450 = 900), and the object would move to the right.
