AP Physics 1 Semester 1 Exam Review

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the formula p = mv, where p is momentum, m is mass, and v is velocity.

Front

How do you calculate momentum?

Back

Momentum (p) is calculated using the formula p = mv, where m is the mass of the object in kilograms and v is its velocity in meters per second.

Front

What is the unit of momentum?

Back

The unit of momentum is kilogram meter per second (kg·m/s).

Front

What happens to the momentum of an object if its velocity doubles?

Back

If the velocity of an object doubles, its momentum also doubles, assuming mass remains constant.

Front

What is the principle of conservation of momentum?

Back

The principle of conservation of momentum states that in a closed system, the total momentum before an event (like a collision) is equal to the total momentum after the event.

Front

What is mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms (kg).

Front

What is the acceleration due to gravity on Earth?

Back

The acceleration due to gravity on Earth is approximately -9.8 m/s².

Front

What is the relationship between force, mass, and acceleration?

Back

The relationship is described by Newton's second law of motion: F = ma, where F is force, m is mass, and a is acceleration.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What does it mean for an object to be at rest?

Back

An object is at rest when it is not changing its position relative to a reference point.
