Conservation of momentum principle
Conservation of momentum principle
Total momentum before = total momentum after event
Type of system for momentum conservation
Type of system for momentum conservation
Closed system
Momentum of a stationary object
Momentum of a stationary object
Zero
Total momentum before (ball mass , velocity , other still)
Total momentum before (ball mass , velocity , other still)
Formula: momentum before (one ball , one still)
Formula: momentum before (one ball , one still)
Total momentum after collision in example
Total momentum after collision in example
(same as before)
After collision: initially stationary ball
After collision: initially stationary ball
Gains velocity and momentum
After collision: initially moving ball
After collision: initially moving ball
Moves with reduced velocity
Sum of two momentums after collision
Sum of two momentums after collision
Equals total momentum before collision
In closed system: momentum before vs after
In closed system: momentum before vs after
Equal
