Forces
Newton's First Law
Object does not move if net force is zero
My ball will not move if net force is zero
Rocket does not move if no gravity, friction, etc.
Net Force= Sum of all outside forces
Newton's Second Law
Can be used to solve for horizontal and vertical acceleration
A = F/M Acceleration is equal to force/mass
A ball moving at 10 newtons has a mass of 20 kg, the acceleration is 1/2 m/s squared
a=
Newton's Third Law
Every action has equal, opposite reaction
Action Force and Reaction Force
When you fire a gun, bullet goes forward, gun kicks back
Forces cause motion
:
Action is the first force
Reaction finishes with equal force
