Conservation of momentum principle
Conservation of momentum principle
In a closed system: total momentum before = total momentum after
System where momentum is conserved
System where momentum is conserved
Closed system
Momentum of stationary object
Momentum of stationary object
Zero
Total momentum before (one ball at , one still)
Total momentum before (one ball at , one still)
Momentum before: moving + stationary ball formula
Momentum before: moving + stationary ball formula
Total momentum after collision
Total momentum after collision
Remains (same as before)
What happens to initially stationary ball after collision?
What happens to initially stationary ball after collision?
Gains velocity and momentum
What happens to moving ball's velocity after collision?
What happens to moving ball's velocity after collision?
Reduced velocity
Sum of both balls' momentum: after vs before
Sum of both balls' momentum: after vs before
Equal (momentum conserved)
