What is the force that slows and stops motion between touching objects?

Back

Front

What do we call a force that brings an object closer?

Back

Pull

Front

How is speed defined, and how does it differ from velocity?

Back

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity 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 = ma).

Front

What is the effect of friction on motion?

Back

Friction opposes motion and can slow down or stop moving objects.
