What is the formula for momentum?
P = M x V
What is Newton’s second law state?
F = M x a
What is the formula for the changing rate of momentum?
F = ^P
—
^t
What is the formula for the impulse
F^t= ^P
What is Hookes Law?
F = K x e
What is Newtons 1st law?
If the resultant force on a stationary object is zero the object will remain stationary. But if the resultant force on a moving object is zero it will carry on moving at a constant momentum.
What is Newtons 3rd law?
When two objects interact the forces they exert on each other are equal in magnitude and opposite in direction.
The law of conservation of momentum states?
In a closed Subsystem the total momentum before equals the total momentum after.
