The Force of Gravity – Homework Answers
About 1 min read
After you have completed the Gravity Homework, you can refer to these answers. Although it is better to have known the answer from your reading, the process of writing the correct answer on your homework sheet will help you remember the concepts.
1. What is gravity?
It is a force at a distance that attract objects to each other.
2. Does a falling body accelerate?
Yes, approximately at a constant acceleration.
3. If you drop an object, it accelerates. When does it stop accelerating?
When it hits the ground. But also, air resistance can cause the acceleration to become zero.
4. What is weight?
The effect of gravity on matter. Weight = g x m.
5. How much does a 180 pound person weigh on the Moon?
About 1/6 or 30 pounds, because the acceleration of gravity (g) on the Moon is 1/6 that on Earth..
6. Why will a 10 pound weight take just as long to hit the ground as a 5 pound weight dropped at the same time form the same height?
Acceleration due to gravity is independent of the mass of the object.
7. Why will a bullet fired from a gun and a bullet dropped from the same height hit the ground at the same time?
.Motion perpendicular to gravity has no effect on the rate an object falls..
