Projectile Motion
The movement of an object that has been thrown or launched through 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 type of 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 is the formula for 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.
When all body parts create force at the same time.
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?
This term describes the ability of the body to resist forces that could cause it to lose its balance, often enhanced by the alignment of the body’s segments and the positioning of the center of gravity
What is static stability
The direct distance between the starting point and the end point 'as the crow flies'
What is displacement?
Transferring momentum from one body part to another when the previous one slows down.
What is the kinetic chain?
long jump, soccer kick, golf hit, hockey flick
What are examples of zero relative release height.
Levers that have a long resistance arm that create speed at the end of the lever
What is a speed multiplier?
In sports and physical activities, this term refers to the ability to maintain equilibrium while performing dynamic movements, often achieved by adjusting the base of support and body alignment
What is dynamic 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?
