Back

A force is a push or pull on an object.

Front

The unit for force is N (Newtons).

Front

What is an example of a force that pulls objects toward the Earth?

Back

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

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = m × a).
