Forces in Year 5 – Gravity

What happens to a ball when we drop it?

We discussed the Hypothesis:

When I drop a large ball and a small ball from the landing, the balls will hit the floor at the same time.

Some of us thought that a large ball would fall faster than a small ball, some of us thought the small ball would fall faster.  Some of us thought the balls would fall at the same rate.

We dropped the balls and discussed the results.

Galileo discovered that everything falls at the same speed. In 1658 he dropped two balls of different masses from the leaning tower of Pisa. He discovered they hit the ground at the same time.
