4.5.7 Momentum Flashcards
1
Q
Momentum equation
A
Momentum = mass x velocity P = m v
2
Q
Momentum units
A
Momentum, p, in kilograms metre per second, Kg m/s
3
Q
Mass units
A
Mass, m, in kilograms, kg
4
Q
Velocity units
A
Velocity, v, in metres per second, m/s
5
Q
What is the conservation of momentum
A
When In a closed system, the total momentum before an event is equal to the total momentum after the event
6
Q
Examples of momentum in an event (collisions)
A
When two objects collide the total momentum before the collision is equal to the total momentum after the collision (in the absence of external forces).
7
Q
What happens when a force acts on an object that is moving, or able to move?
A
A change of momentum occurs
8
Q
What’s the equation for change in momentum ?
A
