Quiz on Modern Physics

What is the principle of inertia as described by Newton's first law?

• An object will change its velocity if no external forces act on it.

• An object will accelerate if a net external force is applied.

• An object will remain at rest unless acted upon by a net external force.

• An object will continue in motion unless acted upon by an external torque.
