Causes of human motion, studying torque and forces |
|
|
What is forced measured in? |
Newtons |
|
|
Aspects of force: |
Magnitude, point of application, direction, and line of action. |
|
|
Types of motion: |
1. Translation/linear * moving in one direction 2. Rotation/angular * not acting through the objects center mass 3. General * Combination |
|
|
What is torque? |
The movement of force. It is Force times distance. |
|
|
Newton's 1st Law of Motion: |
Law of inertia - body continues in its state until acted upon |
|
|
2nd Law |
Law of acceleration - acceleration is proportional to the amount of force in that direction. |
|
|
3rd Law |
Law of action-reaction - for every force there is an equal or opposite force. |
|
|
Forces impacting human movement |
1. External forces - i.e. gravity 2. Internal forces - i.e. joint reaction * elasticity is important (influenced by stiffness, stress, and strain 3. Force - velocity relationship - ??? |
