- Friction is a force resting the motion of an object moving across a surface.
- Pressure is when something has weight or an outside force acting on that object.
- Terminal velocity is when the air resistant is equal and weight of the falling object. because they are directly opposite forces.
- Terminal velocity formula is a=v1-v2/d
- a is acceleration v is velocity i and 2 d is distance.
- How this related to hockey is that when a puck is passed that when it is sliding across the ground there is friction action upon how it moves. a good example is when a hockey player makes a pass. an example for pressure is when you are skating across the ice there is pressure on the skates. terminal velocity is when someone takes a shot and is hit hard as it can be when it is in midair it will only go so fast and that is when it hits its terminal velocity. Review questions:
- What is the force on the skates when skating. gravitey
- A puck is at o m/s then goes to 50m/s in 10 seconds what is the terminal velocity. 5m/s
