Inertia

Front

What is inertia?

Back

Inertia is the tendency of an object to resist a change in its motion.

Front

Which law of motion describes inertia?

Back

Inertia is described by Newton's First Law of Motion.

Front

How does mass relate to inertia?

Back

Heavier objects have more inertia than lighter objects.

Front

What happens to an object's inertia if its mass increases?

Back

The object's inertia increases.

Front

What is an example of inertia in everyday life?

Back

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

Front

What is the relationship between inertia and acceleration?

Back

Inertia resists acceleration; more inertia means more force is needed to change motion.

Front

Can an object have inertia if it is not moving?

Back

Yes, all objects have inertia, whether they are moving or at rest.

Front

What is the formula for calculating inertia in terms of mass?

Back

Inertia is directly proportional to mass; more mass means more inertia.

Front

What is a common misconception about inertia?

Back

Some people think only heavy objects have inertia, but all objects have it.

Front

How does inertia affect motion in space?

Back

In space, objects continue moving in a straight line due to inertia unless acted upon by a force.
