Chapter 7 Newton's laws of motion and momentum Flashcards
1
Q
Define impulse
A
Force x time for which the force acts
2
Q
Newton’s second law
A
The resultant force of an object is directly proportional to the change in momentum /time taken
3
Q
Principle of conservation of linear momentum
A
Total momentum before a collision and after a collision is conserved in a closed system
4
Q
What is Newton’s third law?
A
If object A exerts a force on object B then object B will exert an equal in magnitude and opposite in direction of the same type of force on A.
