Newtons 1st Law

Front

What is a push or pull that can change the motion of an object?

Back

Force

Front

What happens to an object in motion when no net force acts on it?

Back

It continues to move at a constant velocity.

Front

What does Newton's 1st Law of Motion 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 the term for forces that are equal in size and opposite in direction?

Back

Balanced forces

Front

If an object is stationary, what can we say about the forces acting on it?

Back

The forces are balanced.

Front

What is an example of Newton's 1st Law in everyday life?

Back

When a car suddenly stops, passengers lurch forward.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change the motion of an object, while unbalanced forces cause a change in motion.

Front

What is inertia?

Back

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

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia.

Front

What is net force?

Back

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