|
moment of inertia
|
reluctance of a body to resist rotation around the mass around the axis.
|
|
|
impulse
|
change in momentum of an object.
|
|
|
linear motion
|
All body parts moving at the same time in the same direction in a line or parabola track.
|
|
|
angular motion
|
All body parts moving on an axis of rotation in the same direction.
|
|
|
general motion
|
A combination of both angular and linear as the body will be going in one direction, but parts of the body may be rotating on different axis's.
|
|
|
force
|
Any pushing or pulling activity that tends to alter the state of motion of a body.
|
|
|
newtons 1st law
|
An object will stay at rest or remain in its state of motion unless acted upon by an unbalanced force.
|
|
|
torque
|
The turning effect created as a result of force being applied to an object outside its axis of rotation.
|
|
|
newtons 2nd law
|
The total force on a body is the product of the mass of the body by the acceleration.
|
|
|
flattening the arc
|
creating an area of ‘flat line motion’ which allows an increased opportunity to make contact with the ball in desired direction of travel.
|
|
|
newtons 3rd law
|
With every action, there's a positive and equal reaction.
|
|
|
drag/fluid resistance
|
As an object moves through fluid (water/air) it disturbs itThe greater the disturbance to the fluid the greater the transfer of energy from one object to another.
|
|
|
buoyancy
|
Upward force that keeps things afloat. It's used to counteract the effects of gravity and associates with how well the body floats and how high it sits in the liquid.
|
|
|
Bernoulli's principle
|
Resistance created by pressure differential between front & back of an object moving through a fluid.
|
|
|
magnus effect
|
The influence of rotation of an object on its flight path is termed the MAGNUS EFFECT. It is a force due to the movement of articles with a pressure gradient.
|
|
|
lever
|
A lever is a rigid bar-like object that turns around a fixed point (axis) & to which forces are applied at two other points.
