Momentum and Impulse Flashcards
1
Q
Momentum
A
- Product of an object’s mass and velocity.
- Vector Quantity: Magnitude and Direction
- p = m.v
- k.g.m.s-1
2
Q
Collision
A
- Isolated event
- Two or more moving bodies exert a force on each other over a short period of time.
3
Q
Change in momentum
A
Delta p
4
Q
Newtons 2nd law in terms of momentum
A
“The net force acting on an object equals the rate of change of momentum”
5
Q
Conservation of momentum
A
- “The total linear momentum in an isolated system remains constant, is conserved”
- Momentum is always conserved!
6
Q
Elastic Collision
A
- Total kinetic energy is conserved.
- Only occur between microscopic particles.
7
Q
Inelastic Collision
A
- A collision where kinetic energy is not conserved.
8
Q
Impulse
A
- Change in linear momentum of a body
