A) Calculate the force of gravitation between two objects of masses 50 kg and 120 kg respectively, kept at a distance of 10 m from one another. (Ams: 4.02
* 10' N).​

You will be galileo perform the experiment to determine if objects with different mass fall at the same, or different, rates in the air and in a vacuum. (refer to the walk-through video to locate the online lab within the online textbook).

What is the measure of a change in an objects velocity?

Why is the energy that results from a roller coaster's position at the top of a hill referred to as potential energy?
