Newtons Law 3 Flashcards
WHAT IS ACTION-REACTION FORCE FORCES?
Action forces is when an object is being used to apply force to another object to accelerate foward, which then the object pushes back force enough for you to feel it.
WHAT IS AN EXAMPLE OF ACTION FORCE AND REACTION FORCE.
If a tennis ball is hit by a racquet, the racquet applies a force to the ball and the ball accelerates forward.
However, the ball also exerts a force back onto the racquet, which you can feel as you hit the ball.
This is called a reaction force.
WHAT DOES NEWTONS 3RD LAW STATE?
For every action force there is an equal and opposite reaction force.
EXAMPLE OF NEWTONS 3RD LAW?
A sprinter pushes on the starting blocks, which is the action force.
The reaction force is the starting blocks pushing back on the sprinter, propelling them forwards.
