1.24 demonstrate an understanding of Newton’s third law

Newtons Third Law

For every action, there is an equal and opposite reaction.

This means that anything that is object A pushes against object B they will both feel the same force.

To understand this, a few examples:

1. Imagine you are leaning against the wall with your hand. Your hand feels a force and the wall feels the same force. 
2. But what if you punch your hand through a wall? The wall and you still feel the same force but your hand is harder so does not break but the wall does.
3. For the third, imagine if you are an ice skater. You have a partner (who has a smaller mass than you) and you push off of each other. Your partner travels further. This is because of a = f / m. If the mass is greater is means that the acceleration will be less.
