AP Physics 1 Final Exam Review

Front

What happens to the electrostatic force between two point charges when the distance between them is tripled?

Back

The electrostatic force decreases to 1/9 of the original force.

Front

What is the term for knowing both speed and direction?

Back

Velocity.

Front

How is Kinetic Energy defined?

Back

Kinetic Energy is the energy of motion.

Front

During which segment of a race does a runner have the greatest speed if motion sensors recorded segments W, X, Y, and Z?

Back

Segment W.

Front

If the mass of one object doubles, what happens to the gravitational force between two objects separated by a distance r?

Back

The gravitational force doubles.

Front

What is the formula for calculating Kinetic Energy?

Back

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

Front

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

Back

Force = mass × acceleration (F = ma).

Front

What is the principle of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

What is the unit of force in the International System of Units (SI)?

Back

Newton (N).

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).
