Newton's First law

Front

What is Newton's First Law of Motion?

Back

An object at rest will remain at rest, and an object in motion will continue in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

Define inertia.

Back

The tendency of an object to resist a change in its motion.

Front

What are unbalanced forces?

Back

Combined forces that form a net force that is not zero.

Front

What happens to a moving object when no net force acts on it?

Back

It continues to move in a straight line at a constant speed.

Front

Give an example of inertia in everyday life.

Back

A passenger lurching forward in a car when it suddenly stops.

Front

What is a net force?

Back

The overall force acting on an object when all the individual forces are combined.

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it will resist changes in its motion more.

Front

What is the relationship between force and motion according to Newton's First Law?

Back

An object will not change its state of motion unless a net force acts on it.

Front

What is an example of balanced forces?

Back

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

Front

What is the effect of an unbalanced force on a stationary object?

Back

It will cause the object to move.
