Momentum Flashcards
What is Momentum?
The product of the object’s mass and velocity.
What is the formula for Momentum?
P = mv
Momentum = Mass times Velocity.
The greater the mass of an object, or the greater its velocity…
the more momentum the object has.
What is Conservation of momentum?
In a closed system, the total momentum before an event is the same as after the event.
What causes a change in momentum?
When a resultant force acts on an object for a certain amount of time.
A resultant force on an object causes it to…
accelerate:
Force = mass times acceleration.
Acceleration is just change in…
velocity over time:
force = (mass X change in velocity)
/
time
A force applied to an object over any time interval will change…
The objects velocity.
Mass times change in velocity is equal to…
change in momentum.
What is the formula for change in momentum?
F = (mv-mu)
/
t
