Specific heat capacity definition
Specific heat capacity is the amount of energy to raise a materials temperature by 1 degrees C.
1 of 11
Efficiency equation
The efficiency equation is; efficiency= useful power output / total power in.
2 of 11
Gravitational potential equation
Mass x gravity x height
3 of 11
Work done equation
Force x distance moved
4 of 11
Kinetic energy equation
0.5 x mass x velocity squared
5 of 11
Speed equation
Distance/ time
6 of 11
Insulation
Insulation is the ability to trap air in a material and air is a bad conductor of heat, meaning that the particles are spread and cannot trap heat
7 of 11
Energy calculation
mass x specific heat capacity x temperature change
8 of 11
Independent variable
Is the one you change
9 of 11
Dependent variable
Is the one that you keep the same
10 of 11
Control variable
Is the one you keep to ensure that the test is fair
