AP Physics 1 Semester 1 Exam Review

Front

What is the unit for acceleration?

Back

m/s²

Front

What happens to kinetic energy (KE) and potential energy (PE) as a pendulum swings from its highest point to its lowest point?

Back

KE increases and PE decreases.

Front

At which position does a spring have maximum elastic potential energy?

Back

Position C.

Front

In a displacement vector, what is the horizontal component if the vector is 30 km, West?

Back

30 km, West.

Front

What is the missing force when discussing forces acting on an object in equilibrium?

Back

Normal force.

Front

Define kinetic energy (KE).

Back

The energy of an object due to its motion, calculated as KE = 1/2 mv².

Front

What is gravitational potential energy (PE)?

Back

The energy an object possesses due to its position in a gravitational field, calculated as PE = mgh.

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 formula for calculating acceleration?

Back

a = (v_f - v_i) / t, where v_f is final velocity, v_i is initial velocity, and t is time.

Front

What is the difference between scalar and vector quantities?

Back

Scalar quantities have magnitude only, while vector quantities have both magnitude and direction.
