AP Physics 1 Semester 1 Exam Review

Front

What is the net force acting on an object if the forces are 400 N Up and 400 N Down?

Back

400 N Down

Front

If the net force acting on an object is equal to zero, what can we say about the forces?

Back

The forces are balanced.

Front

What does a graph showing a downward slope indicate about an object's motion?

Back

Negative acceleration.

Front

In which position of a spring is the elastic potential energy maximized?

Back

Position C.

Front

What is Newton's second law of motion?

Back

Force is equal to an object's mass times its acceleration.

Front

Define balanced forces.

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What is unbalanced force?

Back

Forces that are not equal and opposite, causing a change in motion.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What is the law of inertia?

Back

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

Front

What does it mean if an object is in free fall?

Back

The only force acting on the object is gravity.
