Physics - Newton's Laws

Newton’s First Law

Newton’s First Law

Objects will remain at rest, or move with a constant velocity unless acted on by a resultant force

Newton’s Second Law

The acceleration of an object is proportional to the resultant force acting on it and inversely proportional to the object's mass. F=ma

Newton’s Third Law

Whenever two bodies interact, the forces they exert on each other are equal and opposite 

resultant force?

F=ma

Conservation of Momentum

In a closed system, the total momentum before an event is equal to the total momentum after the event

momentum

P=mv

speed

s=d/t

acceleration

a=(v-u)/t

velocity

v=u+at or v^2=u^2+2as

displacement

s=ut+1/2at^2 or s=1/2(v+u)t

force

F=(mv-mu)/t or F=ma
