- 1Define Scalar QuantitiyIt is one that has A magnitude but not a direction
- 2Define Vector QuantitiyIt is one that has a Magnitude and Direction
- 3Define SpeedIt is Distance per unit time
- 4Define DisplacementIt is distance moved in a stated direction
- 5Define VelocityIt is the displacement per unit time, or change in displacement/time
- 6Define AccelerationIs the rate of change of Velocity
- 7Define The NewtonIt is the force required to accelerate a 1 Kg object at 1 \(MS^-2\)
- 8Define The Moment of a ForceIt is the force multiplied by the perpendicular distance from a stated point (or pivot)
- 9Define CoupleIs a pair of equal and parallel but opposite forces, which tend to produce rotation only
- 10Define DensityIt is Mass per unit Volume
- 11Define PressureIt is force per unit area
- 12Define The JouleIt is the work done when a force of 1 Newton moves it's point of application 1 Metre in the direction of the force
- 13Define The Conservation of EnergyIt is in any closed system, energy may be converted from one form to another but cannot be created or destroyed
- 14Define EnergyIs is the stored ability to do work
- 15Define Gravitational Potential EnergyIt is the energy stored in an object due to it's position in a gravitational field
