Motion and Momentum Flashcards
1
Q
Newtons first law of motion
A
An object stays at rest or moves with uniform velocity unless it is acted upon by an external force
2
Q
Newton’s second law of motion
A
The rate of change of momentum of a moving body is proportional to and in the same direction as the force acting on it
3
Q
What is Newton’s second law of motion equation
A
F= ma
F= (mv-mu)/ t
4
Q
Newton’s third law of motion
A
If an object A exerts a force on an object B then object B exerts an equal and opposite force on object A
