What happens when two objects collide?

Back

When two objects collide, they exert forces on each other, which can change their motion.

What is the relationship between mass and force?

Back

The greater the mass of an object, the more force is required to change its motion.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes direction.

Front

What is inertia?

Back

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

Front

What is the effect of friction on motion?

Back

Friction is a force that opposes motion, causing objects to slow down or stop.
