If a car accelerates from rest to 20 m/s in 4 seconds, what is its acceleration?

Back

5 m/s²

Front

Which law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass?

Back

Newton's Second Law

Front

What is the definition of force?

Back

A push or pull on an object resulting from its interaction with another object.

Front

What is the unit of force in the International System of Units (SI)?

Back

Newton (N)

Front

What does Newton's First Law state?

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 acceleration?

Back

The rate of change of velocity of an object.
