Write a word problem involving potential energy using the following variables: Potential Energy = 16 J
Acceleration due to gravity on Earth = 9.8 m/s^2
Mass = 7 kg
Think about what information you are missing and what the problem could be asking you to solve. Make sure to include the solution to your problem. (Potential energy = 9.8 x mass x height)

Data just came in about the space pod's mission and the thrusters fired for exactly the same about of time and at the same force as they have in past missions. Nothing about the pod's thruster force was different. Based on this new evidence, neither of our previous claims could be true!


We are left with the same question: why didn't the pod dock like it was supposed to do?
What new theories do you have?

if you dig a hole through the earth, from one hemisphere to the other, and drop a tennis ball into it, would it get stuck at the center, since thats where gravity's at, or would it pop up out the other side??

what happens to suns energy while it travels to earth's atmosphere

A: Some of it is destroyed in Earth's atmosphere.
B: It is completely trapped by Earth's surface.
C: It is all reflected back into space.
D: Some of it reaches Earth's surface.

A group of students is tasked with developing a checklist for determining whether a material undergoes a chemical or physical change. The students make a preliminary list of properties that they can test and classify each as either a chemical or physical property.

Chemical Property Physical Property
bubbles when treated with acid color
burns when placed in a candle flame odor
density hardness
boiling point mass
dissolves in water melting point
Several other students in the class claim that the checklist is incorrect.

What change should the group make to the checklist to correct their mistake?


Boiling point and density should be moved to the physical property side of the list, and color and odor should be moved to the chemical property side of the list.


Boiling point and density should be moved to the physical property side of the list, and hardness and mass should be moved to the chemical property side of the list.

Dissolves in water and boiling point should be moved to the physical property side of the list, and odor and mass should be moved to the chemical property side of the list.

Density and boiling point should be moved to the physical property side of the list.
