|
work= |
force x distance. W=FxD. Joules, Newtons, distance |
|
|
pressure |
P=F divided by A. p= force/weight of an object dv b surface area |
|
|
average speed |
V= D dv b T. V(average speed)= distance dv b time |
|
|
acceleration |
a= triangle V dv b triangle t. acceleration= change in speed dvb change in time |
|
|
kinetic energy |
energy an object has bc its moving. Ek= 1/2 M x V2 (V squared). Kinetic energy= 1/2 mass x speed. mass- kgs. speed- ms-1 (miles per second.) |
|
|
Gravitational potential energy |
gained if object is raised upwards. Ep. triangle Ep= mass x gravity x triangle height. increase of Ep = work done to lift object. Gravity= 10 newtons |
|
|
power |
rate of which work is done. watt of power= transfer of one joule. p= W dvb t. Power= work donedvb time taken |
|
|
A a |
surface area acceleration |
|
|
a A |
acceleration surface area |
