Law of Inertia

What is the property of matter that causes objects to resist change in motion?

• mass

• force

• inertia

• gravity

Answer explanation

Inertia causes objects to resist changing their speed, direction, or state of rest

What tells us how much an object will resist a change in motion?

• mass

• inertia

• force

• gravity

Answer explanation

The greater the mass, the greater resistance to change in motion

What is Newton's Law of Inertia?

• An object in motion will stay in motion and an object at rest will remain at rest unless an unbalance force acts on it

• for every action there is an equal and opposite reaction

• force = m x acceleration

• speed = distance/time

Answer explanation

This is known as Newton's First Law of Motion

Why do objects in motion always come to a stop?

• an unbalanced force acts on them

• that is Newton's 4th law of motion

• objects in motion never come to a stop
