Front

Which of Newton’s laws states that an object moving at a constant velocity keeps moving at that velocity unless an unbalanced net force acts on it?

Back

Front

What does Newton's Third Law state?

Back

For every action there is an equal and opposite reaction.

Front

What is force?

Back

A push or pull exerted on an object.

Front

What is the formula for calculating force?

Back

F = m x a (Force = mass x acceleration)

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass.

Front

What is an example of balanced forces?

Back

Two people pushing a car in opposite directions with equal force.

Front

What is an example of unbalanced forces?

Back
