The movement of an object that has been thrown or launched throw the air.
What is projectile motion?
The area beneath a person that is in contact with a supporting surface.
What is base of support?
Gravitational force.
What is a non-contact force.
Angle of release, height of release, speed of release
What are the 3 subprinciples of projectile motion.
A wheelbarrow.
What is an example of a second class lever?
The central point around which the mass of a person is distributed.
What is centre of gravity?
mass and acceleration.
What makes force / contributes to force?
What is internal force?
The line along which a projectile travels.
What is trajectory?
Fulcrum, force, resistance.
What are the three parts of a lever?
When a person's line of gravity lands in the centre of their base of support.
When is a person most stable?
A combination of linear motion and angular motion.
What is general motion.
Long jump, high jump, pole vault.
What are examples of simultaneous summation of force.
the angle at which both vertical and horizontal forces are equally applied to the projectile to maximise the distance it will travel
What is optimal angle of release?
The applied force is between the fulcrum and the resistance.
Where is the applied force in a third class lever?
Why do males have a lower centre of gravity than females?
The unit of measure is metres per second squared.
What is the unit of measure for acceleration?
Transferring momentum from one body part to another when it is at its maximum velocity.
What is force and velocity generated by body parts?
long jump, soccer kick, golf hit, hockey flick
What are examples of zero relative release height.
Levers that have a long force arm that requires less effort to move more resistance.
What is a force multiplier?
Lower centre of gravity. Increase base of support. Keep line of gravity in centre of base of support.
How do you maximise stability?
a measure of how quickly or slowly the velocity of an object changes.
What is acceleration?
Using the larger body parts like legs, torso and hips first, then passing on to shoulders, arms, wrist.
What is order and timing of body parts?
