Momentum And Impulse Flashcards
1
Q
Define momentum.
A
It is the product of the mass of the object and its velocity.
2
Q
Define newton’s second law in terms of momentum.
A
The net force acting on an object is equal to the rate of change of momentum.
3
Q
Define newton’s third law.
A
When object A exerts a force on object B, object B will exert an oppositely directed force of equal magnitude on object A.
4
Q
Define the law of conservation of momentum.
A
The total linear momentum of an isolated system remains constant.
5
Q
Define an elastic collision.
A
One in which both momentum and kinetic energy are conserved.
6
Q
Define an inelastic collision.
A
One in which only momentum is conserved.
7
Q
Define impulse.
A
The product of the net force and the contact time.
