The rate of change of an objects velocity.
The distance travelled by a vehicle from the moment when brakes are applied untill the vehicle comes to a stop.
Centre of gravity
The point where the entire weight of an object appears to act.
The mass per unit volume of material.
The distance moved by an object in a particular direction (measured from a fixed starting point).
Useful output energy/ total input energy x 100
The net forces acting on the object are equal to zero.
The torque of the object is equal to zero.
The force that will give a 1KG mass an acceleration of 1 ms^-2.
The moment of a force about a point is the magnitude of the force, multiplied by the perpendicular distance of the point from the line of the force.
The rate at which energy is transferred or the rate at which work is done.
The force acting normally per unit area of surface. p=F/A
The sum of the braking distance and the thinking distance.
