MECHANICS
I made a spider diagram to help me in mechanics, i used Edecel AS physics students' handbook to help me make this.
It helps me to put all the basics of it into a brain storm. :)

- MECHANICS
- MOTION
- speed = distance/ time
- velocity= displacement/ time taken
- a = v-u/t
- vectors
- vectors can be represented by arrows. length of the arrow represents the magnitude,and the direction of the arrow represents the direction of the arrow.
- vectors can be drawn as triangles whenever more than one vector is applied.
- scalar
- only has either size or magnnitude
- acceleration is defined as the rate of the change of velocity with time
- FORCES
- ENERGY AND POWER
- law of conservation of energy
- energy cannot be created nor destroyued
- work done = force x distance moved in direction of force
- potential energy
- NounThe energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.
- efficiency
- efficiency= useful energy got out (kinetic energy /energy put in
- power
- power = energy transferred/ time taken
- power = work done / time taken
- efficiency= useful energy output/ energy input x 100%
- efficiency
- efficiency= useful energy got out (kinetic energy /energy put in
- efficiency
- law of conservation of energy
- MOTION
