Slide 1

    Mechanic's
    Level 1 Science 1.1 Mechanic's AS 90940 External 4 Credit's  This achievement standard involves demonstrating understanding of aspects of mechanics and may include using methods when solving related problems.

Slide 2

    Velocity V = D / T
    Speed is how fast something is going.  Velocity is how fast something is changing position in a certain amount of time. Constant Velocity means an objects velocity is not changing. Non- Constant Velocity means the object is Accelerating or decelerating. The Gradient of a distance vs time graph is the velocity. Unit is ms-1

    Forces F = M x A
    Forces change the speed of an object Net force is the overall force its like the leftover force when everything else is balanced out. Weight is the downward force due to gravity (N) Mass is the amount of matter in an object (kg) Measured in Newtons (N Balanced forces are were all the forces cancel out therefore there is no net force and the object is stationary or moving at a constant speed.Unbalanced forces are when the forces dont balance in a certain direction causing a net force which will mean the object is accelerating.

    Energy
    Caption: : Energy
    Energy isn't created or destroyed it can only be transferred into different types of energy.Gravitational Potential EnergyElastic Potential EnergyChemical potential EnergyHeat + Light or Sound EnergyMeasured in joules J (make sure it is a capital)Change into kg first when measuring mass
