Physics I 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

What is the unit of momentum?

Back

The unit of momentum is kg * m/s.

Front

How does momentum change when speed is doubled?

Back

When the speed of an object is doubled, its momentum also doubles.

Front

What is the formula for calculating momentum?

Back

The formula for calculating momentum is p = mv, where p is momentum, m is mass, and v is velocity.

Front

What is the relationship between force and momentum?

Back

The change in momentum of an object is equal to the impulse applied to it, which is the product of force and the time duration over which it acts.

Front

What is the unit for speed?

Back

The unit for speed is m/s.

Front

What does a net force of 0 N indicate about an object's motion?

Back

A net force of 0 N indicates that the object is either at rest or moving at a constant velocity.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, typically measured in m/s².

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 in uniform motion?

Back

An object is in uniform motion if it moves at a constant speed in a straight line.
