Brian from Science World demonstrates movement and collisions using balls. He explains how momentum works through simple experiments, including a demonstration with Newton's Cradle. Safety tips are provided, and viewers are encouraged to explore further with resources available online.

What happens when two balls of different sizes are dropped from the same height at the same time?

• The smaller ball hits the ground first.

• Neither ball hits the ground.

• The larger ball hits the ground first.

• Both balls hit the ground at the same time.

What is momentum?

• The speed of an object.

• The weight of an object.

• The amount of movement an object has.

• The size of an object.

What happens when a small ball is placed on top of a bigger ball and they are dropped together?

• The big ball does not bounce.

• The small ball bounces higher than usual.

• The small ball bounces lower than usual.

• Both balls bounce the same height.

Why should you not put your face near the bouncing balls during the experiment?

• The balls might break.

• The balls might stop bouncing.

• The balls might hit your face.

• The balls might get lost.
