- Work is how much power you half to do something.
- Power is how much energy is in the object.
- Kinetic energy is how much energy there was the total amount.
- Potential energy is how much stored energy.
- Conversation of energy is all the saved energy.
- w=fd w stands for work, f stands for force, d stands for distance. p=w/t p stands for power w stand for weight t stands for time. (ke=1/2mv^2) ke stands for kinetic energy, m stands for mass, v stands for velocity squared. pe=mgh (pe) stands for potential energy, m stands for mass,g stands for gravity,h stands for height.
- How these all related to hockey is that you go to to one side of the rink you do work. when you are skate trying to gt the puck you are doing work .kentic energy related because when you are going fast as you can that the top energy . potential energy is when a hockey player starts to skate because he has all this energy he is about to use. conservation of energy comes into effect when you start to slow down and just free skating
Review questions: - Do you do work if you skate to one end of the rink? yes
- how much power do you have if run to down a feid if you are 100kg and run down in 15 seconds. 6.6667
