What is Mass?
|
The amount of matter that makes up an object
|
|
| 2 |
What is Weight?
|
The amount of force the earths gravity has on any object
|
|
| 3 |
What is Velocity?
|
It is the measurement of the rate of positional change
|
|
| 4 |
The two variables of Velocity are?
|
Speed and Direction
|
|
| 5 |
What is Momentum?
|
It is the measure of the amount of motion 'posessed' by a moving object
|
|
| 6 |
How can momentum be expressed as a mathematical formula?
|
momentum= mass x velocity
|
|
| 7 |
Newtowns Third Law of Motion is also known as?
|
Conservation of Momentum
|
|
| 8 |
How can the velocity of an object be changed?
|
Apply more of less force
|
|
| 9 |
Name the three classes of levers?
|
1st Class Lever 2nd Class Lever 3rd Class Lever
|
|
| 10 |
What is friction?
|
Friction opposes movement
|
|
| 11 |
What is linear motion? Give two sporting examples.
|
All parts of the body that move in the same direction at the same time. 1- Skier down a slope...
|
|
| 12 |
What is Angular motion? Give two sporting examples
|
All parts of the body rotate in the same direction at the same time at a fixed point 1- Hammer...
|
|
| 13 |
What is General Motion?
|
General motion occurs when linear and angular motion occur together
|
|
| 14 |
What is torque?
|
Torque is the action that causes a change in a bodys rotation
|
|
| 15 |
What is velocity?
|
Velocity measures the positional charge of an object
|
|
| 16 |
What is inertia?
|
Inertia is the tendancy of an object to maintain its velocity
|
|
| 17 |
What is impulse?
|
Impulse is the amount of change in momentum
|
|
| 18 |
What is elasticity?
|
Elasticity refers to the abiltiy of objects to give and then return to their original shape...
|
|
| 19 |
What is force summation?
|
It is the summation of momentum and allows a performer to maximise the speed of their body...
|
|
| 20 |
Difference between Accuracy and Force Summation?
|
Accuracy requires a force to be applied in a certain direction whilst force summation...
|
|
| 21 |
What is moment of inertia?
|
It is the tendancy an object has to maintain its angular momentum
|
|
| 22 |
What is angular momentum?
|
It is a measure of the amount of rotation posessed by the body
