Suppose you throw a ball straight up into the air. Describe the changes in the acceleration of the ball.

As the caterpillar climbs, its potential energy is increasing. what source of energy has been used to effect this change in potential energy?

An object with a mass of 11.5kg falls 6.69m what will the air's internal energy increase by from this falling object?

3. Ms. Johnson can bench press 150 kg from 0.7 m from the ground to 1.5 m above the ground. a. How much weight (not mass) did Ms. Johnson lift? Put down Givens, Solving For, Equation, Substitution, Answer with Units b.

two test cars of equal mass moving towards each other collide on a horiontal frictionless surface. Before the collision, car A has a constant speed 20m/s while car B has a constant speed of 12m/s.

What is true of both gravity and magnetism? Both are dependent on mass. Both forces can act without objects touching. Both forces are directly proportional to the distance between the objects. Neither is a fundamental force of nature.

two objects each weighing 2kg are lifted through the same distance in 4s and 1s respectively. which scenario requires more work?

A rocky space object of varying size

Three balls are kicked from the ground level at some angles above horizontal with different initial speeds. All three balls reached in their paths the samemaximum height.
