Hey thanks for coming over. Lets go play in my room!
Let's see who can jump the highest on your bed.
Okay its definitely going to be me haha
As they get ready to jump their feet push into the mattress causing an action.
yes i am!
Are you ready?
After their feet push into the mattress, the mattress pushing up and forward allowing them to jump into the air. That is the reaction.
Im going higher!
Wow Im going so high!
Newtons third law states that for every action(force) there is an equal and opposite reaction.
Object A exerts a force on object B, then object B also exerts an equal and opposite force on object A
In this case me and my friend are object A and the mattress is object B. We exerted force into the mattress and then the mattress exerted an equal or opposite force allowing us to jump.
