Front

What is Newton's 1st Law of Motion?

Back

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 does inertia refer to in physics?

Back

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

Front

How does mass affect gravitational force?

Back

Gravitational force increases with the mass of the objects.

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = ma).
