Momentum

Cards (9)

Define momentum
The product of an object's mass and velocity
Describe the momentum of an object at rest
Zero, because it has no velocity
What is the equation of momentum? 
p = mv
Momentum= mass x velocity
What is the principle of momentum?
In a closed system, the total momentum before an event equals the total momentum after the event
State the condition for momentum to be conserved in a collision
If the system is closed! Meaning, there is no external force acting on it, and energy within the system remains constant
Define impulse
The product of force and the time duration for which it acts
What is the equation for calculating impulse?
impulse = FΔt
impluse= force x change in time
What is the relationship between impulse and change in momentum?
Impulse is equal to the change in momentum of an object
State the equation for force in terms of momentum
Force= change in momentum / change in time
