What is friction?

Back

A force that opposes the motion of an object when it is in contact with another surface.

Front

What is mass?

Back

The amount of matter in an object, usually measured in kilograms.

Front

What is acceleration?

Back

The rate at which an object's velocity changes over time.

Front

What is kinetic energy?

Back

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

Front

What is the relationship between mass and force?

Back

According to Newton's second law, force equals mass times acceleration (F=ma). More mass requires more force to accelerate.

What happens to an object when a net force acts on it?

Back

The object will accelerate in the direction of the net force.

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 direction.

Front

What is Newton's first law of motion?

Back

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