-weather conditons -road surface -poor breaks -tyres (tread, inflation) -speed -mass of carji |
|
|
Things that affect the thinking distance |

|
|
What is the thinking distance |
The distance travelled before our brains react to danger |
|
|
What is the breaking distnace |
The distance travelled by the car,after the breaks have been applied, to stop completely |
|
|
Momentum |
P/MxV |
|
|
Force equation |
F=MA |
|
|
Acceleration equation |
A=V-U/T |
|
|
Equation relating momentum to force |
F= Mv-Mu / T |
|
|
Work definitions |
-when a force makes something move, energy is transferred in the direction of movement, the amount of energy is called the work done -If there has been ANY transfer of energy, we also define this as work having been done |
|
|
Equation for work done |
E / FD (e can also be swapped for w- work done) E- j F- N D-m |
|
|
Equation for power |
Power= work done / time taken (work done can also be swapped with energy transferred) P- watts W- J T- s |
|
|
Equation for kinetic energy |
KE = 1/2 x M x V(^2) KE- j M- kg V- (m/s)2 |
|
|
Gravitational potential energy |
M x G x change in H Mass in kg GPE: kg m^2/s^2 (like all types of energy) |
