- Momentum is when an object is moving and it speeds up as it is moving in its path.
- Impulse is how much power you put in something to move it. bouncing is when something hits then hits back up elastic momentum is when something is moving then gets hit and sticks together after they hit. inelastic is when something is moving and they hit together and then bounce off of each other when the hit.
- The formula for momentum is p=mv p stands for power, m for mass, and v for velocity
- Formula for impulse is impulse=ft f stand for feet t stands for time. at the top is a diagram of a momentum.
How it relates to hockey:
This relates to hockey because when you are skating or hit the puck it has momentum. How impulse comes into play is that when you go to skate you half to put work into it to skate and get the puck. also when you pass the puck you put impulse to pass the puck. Inelastic collisions would come into play if you where going for the puck and you both hit together and bounced off of each other and this is how that would relate.
An elastic collision would be if would be is you where both going for the puck and and both hit together and stuck together and fell down and hit the ice.
Review questions:
Two hockey are fighting for the puck and hit each other and both fall to the ground this is an example of what kind of collision? inelastic collision
A hockey player has a mass of 100kg and is skating at 10m/s what is his momentum. 10ms^2
