Question 23 of 32

What is the principle of inertia?

Choose 1 answer

An object will remain at rest or in uniform motion unless acted upon by an external force.

An object in motion will eventually come to rest due to friction.

The force applied to an object is directly proportional to its acceleration.

For every action, there is an equal and opposite reaction.
