Answer 1

-Stretching: Forces in Opposite Direction, away from the Object.

-Bending: Forces that Distort the Object.

-Compressing: Forces in Opposite Directions Towards the Object.

Question 2

-The Weight of the Swimmer.

-The Reaction Force from the Block to the Diving Board.

Question 6

What are the 2 types of Deformation a Shape can go through? (2)

Answer 6

-Elastic.

-Inelastic.

Question 7

What is ‘Elastic Deformation’?

Answer 7

When Objects Return to their Original Shape when the Stretching Force is Removed.

Question 8

What is ‘Inelastic Deformation’?

Answer 8

When Objects Remain Stretched, and do not Return Completely to their Original Shape, even when the Stretching Force is Removed.
