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 inertia?

Back

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

Front

Which factor does inertia depend on?

Back

The mass of the object.

Front

Give an example of inertia in everyday life.

Back

A book remaining on a table until someone moves it.

Front

What happens to an object in motion if no external force acts on it?

Back

It continues to move at a constant velocity.

Front

What is the relationship between mass and inertia?

Back

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

Front

What is acceleration?

Back

The rate of change of velocity of an object.

Front

If you feel a change in velocity, what are you experiencing?

Back

Acceleration.

Front

What is a net force?

Back

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

Front

How does friction affect motion?

Back

Friction opposes the motion of an object, causing it to slow down or stop.
