William 29

Hi Everyone,
Here is my explanation on force arrow diagrams and how arrows represent forces.
When I push the ball up in the air gravity will pull the ball back to the ground.
If I have a heavy ball you would need more force to push it into the air and it would fall to the ground easier because of gravity.
If there was a big and little arrow the big arrow would be the stronger force.
IF you had a small object the arrows would be smaller and you would not need as much force as you would need for a big object.
From William
