Distance time graph
If an object moves in a straight line, how fair it is from a certain point can be represented by a distance time graph.
3 of 26
Gradient of a distance time graph
The speed of an object can be determined from the gradient of a distance time graph.
4 of 26
Object accelerating
If an object is accelerating its speed a any particular time can be determined by finding the gradient of the tangent of the graph at any time.
5 of 26
Velocity
Speed in a given direction.
6 of 26
Velocity equation
V = S/T

Acceleration of an object
Shown on a velocity time graph
9 of 26
Distance travelled
Can be shown from the area under a velocity time graph.

Resultant force effects
Whenever two objects interact, the forces they exert on each other are equal and opposite.
11 of 26
Resultant force
A number of forces acting at a point may be replaced by a single force that has the same effect on the motion as the original forces all acting together. The single force is the resultant force.
12 of 26
Resultant force acting on an object
May cause a change in its state of rest or motion.
13 of 26
If the resultant force on a stationary object is zero
The object will remain stationary.
14 of 26
If the resultant force on a stationary object is not zero
The object will accelerate in the direction of the resultant force.
15 of 26
If the resultant force on a moving object is zero
The object will continue to move at the same speed and in the same direction.
16 of 26
If the resultant force on a stationary object is not zero
The object will accelerate in the direction of the resultant force.

Force equation
F = M x A

Momentum equation
P = M x V
19 of 26
Conservation of momentum
The total momentum is equal to the total momentum after the event.
20 of 26
Force and change of momentum equation
F = change in momentum/time

Force and braking
When a vehicle travels at steady speed the restive forces balance the driving force.
22 of 26
Resistive force
Caused by air resistance.
23 of 26
Greater the speed
The greater the braking force needed to stop in a certain distance.
24 of 26
Stopping distance
The sum of the distance the vehicle tearless during the driver reaction time and distance it travels under the braking force.
25 of 26
A drivers reaction time
Can be effected by tiredness, alcohol, drugs
