Chapter 1 (Gr12) - Momentum & Impulse Flashcards
1
Q
Momentum of an object?
A
The product of the mass and velocity of the obj.
2
Q
Newton’s second law in terms of momentum
A
The net force of an obj. is equal to the rate of change of momentum.
3
Q
Impulse
A
The product of the net force and the contact time.
4
Q
Collision
A
An interaction between 2/more obj. during which they exert force on one another for a specific time interval.
5
Q
Law of conservation of momentum?
A
The total linear momentum of an isolated system remains conserved.
6
Q
Elastic Collision
A
Collision in which both momentum & Ek are conserved.
( ΣEki = ΣEkf )
7
Q
Inelastic collision
A
Collision in which ONLY momentum is conserved.
( ΣEki Not = ΣEkf )
