| what are the 3 primary factors affecting Trajectory? | 1) Angle of release 2) Relative height of release 3) Speed of release |
| which angle of release is best when h=0? | 45 degrees |
| What is the Realtive Height of Release (RHR)? | RHR=release height-landing height |
| Why don's swimmers use such a small angle of take-off? | b/c 45 degrees would take too long and to maximize horiz. velocity |
| What are the 3 charcteristics of force? | 1) Magnitude 2) Direction 3) Point of application |
| What is a force that produces translation & rotation? | eccentric force |
| The natural property of a body to resist changes in its state of motion | Inertia |
| Direct measurment of a body's resistance to change in linear motion | Mass |
| What is the angular form of inertia? | Moment of intertia |
| Newtons 1st law of motion? | In the absence of a net force, the state of motion of an object will not change |
| Newtons 2nd Law of Motion? | The sum of all forces acting on an object = mass X accel. |
| Newton's 3rd Law of Motion? | If one body exerts a force on a 2nd body, teh 2nd body exerts |
