MOMENTUM & IMPULSE Flashcards
1
Q
Newtons’s First Law
A
Law of Inertia
- desire to stay in a constant state
- amount of inertia in a system is proportional to its mass
2
Q
Newton’s Second Law
A
Law of Momentum -momentum= mass * velocity -object in motion has momentum -a larger mass= greater momentum Units (kg m/s)
Impulse: change of momentum
Impulse=force*time
3
Q
Newton’s Third Law
A
Law of Action and Reaction
- for every force applied there is a reaction force equal to the applied force
- reaction force can generate movement
- if sum of all forces acting on a system =o, then there is no movement
