Newtons 3rd Law
Term | Definition |
---|---|
Newtons' third law | for every action there is an equal and opposite reaction |
action/reaction force pair | The force that is exerted on an object and the force that the object exerts back |
opposite | the reverse of something else |
equal | balanced |
action force | a force that is exerted on an object |
reaction force | a force that is exerts BACK on an object |
single object | balanced forces act on |
different objects | action reaction forces act on |
if the action force is the bat hitting the ball what is the reaction force? | Ball hits the ball |
if the action force is the man pushing the ca what is the reaction force? | the car pushes back on the man |
if the action force is the wings of the bird pushing downward what is the reaction force? | the air is pushing back on the bird moving it upwards. |
if the action force is the wheels on a car gripping the road, what is the reaction force? | the road is pushing the wheels of the car in the opposite direction moving the car foward |
if the action force is the fishes using its fins to push the water backwards what is the reaction force? | the water is pushing back on the fish's fins causing it to move forward |
Newtons First Law | An object at rest will stay at rest. An object in motion will stay in motion unless acted upon by an unbalanced force. |
Newton's Second Law | Force equals mass times acceleration. |
Isaac Newton | The greatest mathematican and physicist who discovered gravity and how things move. |
