AP Physics 1 Final Exam Review

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object possesses due to its motion, calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

How do you calculate Kinetic Energy?

Back

Kinetic Energy (KE) = 1/2 mv², where m is the mass of the object and v is its velocity.

Front

What is the relationship between mass and kinetic energy?

Back

Kinetic energy is directly proportional to the mass of the object; as mass increases, kinetic energy increases if velocity remains constant.

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is a Field Force?

Back

A Field Force is a force that acts at a distance, such as gravitational force, without direct contact between objects.

Front

What is the difference between contact forces and field forces?

Back

Contact forces require physical contact between objects (e.g., friction), while field forces act over a distance (e.g., gravity).

Front

What does a straight line on a speed vs. time graph indicate?

Back

A straight line on a speed vs. time graph indicates constant acceleration.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, calculated as PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

How do you calculate the height from which an object falls using kinetic energy?

Back

Using the formula PE = KE, where PE = mgh and KE = 1/2 mv², you can solve for height (h) as h = KE/(mg).

Front

What is the formula for gravitational force?

Back

The formula for gravitational force is F = G(m1*m2)/r², where G is the gravitational constant, m1 and m2 are the masses, and r is the distance between their centers.
