AP Physics 1 Semester Review

Front

What is the formula to calculate acceleration?

Back

a = F/m, where 'a' is acceleration, 'F' is net force, and 'm' is mass.

Front

What is the Law of Inertia?

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 difference between scalar and vector quantities?

Back

Scalar quantities have only magnitude (e.g., mass, temperature), while vector quantities have both magnitude and direction (e.g., velocity, force).

Front

What is the formula for calculating speed?

Back

S = d/t, where 'S' is speed, 'd' is distance, and 't' is time.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = ma).

Front

What is the principle of conservation of momentum?

Back

In a closed system, the total momentum before an event is equal to the total momentum after the event.

Front

What is gravitational potential energy?

Back

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

What is kinetic energy?

Back

The energy of an object due to its motion, calculated as KE = 1/2 mv², where 'm' is mass and 'v' is velocity.

Front

What is the formula for work done by a force?

Back

W = Fd cos(θ), where 'W' is work, 'F' is force, 'd' is displacement, and 'θ' is the angle between the force and displacement.

Front

What is the definition of a force?

Back

A push or pull on an object that can cause it to accelerate, measured in Newtons (N).
