What is the formula for calculating force?

Back

Force = mass × acceleration (F = ma)

Front

What is inertia?

Back

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

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.

Front

What is gravitational force?

Back
