Good Form(ulae)
Is equal to the distance covered divided by the time taken to cover the distance
What is speed?
Occurs when a ball or object rotates backwards causing it to fall slowly at the end of flight
What is backspin?
Is a science concerned with forces and the effect of these forces on and within the human body
What is biomechanics?
Refers to the amount of matter in a body
What is mass?
Refers to the rate of positional change of an object and is calculated using displacement divided by the time
What is velocity?
Is the force that opposes the forward motion of a body or object, reducing its speed or velocity
What is drag?
Is an imaginary vertical line passing through the centre of gravity and extending to the ground
What is line of gravity?
Of a body or object refers to its mass per unit volume
What is density?
Takes place when a body and all parts connected to it travel the same distance in the same direction and at the same speed
What is linear motion?
Refers to drag created by the shape and size of a body or object
What is profile drag?
Is the point at which all the weight is evenly distributed and about which the object is balanced
Is the upward force on an object produced by the fluid in which it is fully or partially submerged
What is buoyant force?
Is the movement of a body from one location to another in a particular direction, or an ‘as the crow flies’ measurement
What is displacement?
Refers to a thin film of the fluid medium sticking to the surface area of the body or object through which it is moving
What is surface drag?
Refers to an imaginary area that surrounds the outside edge of the body when it is in contact with a surface
What is a base of support?
An area of turbulence behind an object moving through a fluid
What is wake?
The rate at which velocity changes in a given amount of time
What is acceleration?
Explains why spinning objects such as cricket and golf balls deviate from their normal flight paths
What is the magnus effect?
Is the component of a force that acts at right angles to the drag
What is lift?
Is the centre of gravity of a volume of water displaced by an object when it is immersed in that water
What is centre of buoyancy?
