What is the acceleration of a tennis ball and a solid steel ball dropped from the same height in the absence of air resistance?

Back

They have the same acceleration.

Front

What is the equation to calculate momentum?

When a ball is dropped, does it fall with a constant velocity until it strikes the ground?

Back

False

Front

What is the definition of momentum?

Back

Momentum is the product of an object's mass and its velocity.

Front

State Newton's First Law of Motion.

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is the formula for gravitational potential energy?

Back

PE = mgh

Front

What does the slope of a position-time graph represent?

Back

The slope represents the velocity of the object.

Front

What is the relationship between force, mass, and acceleration according to Newton's Second Law?

Back

F = ma (Force equals mass times acceleration).
