This resource is a simple worksheet that you can use with your class once you have taught the efficiency calculations.
This worksheets helps students to:
Convert units
Simple calculations
Worded calculation questions
Rearranging the equation questions
Application questions
This can also be used as homework to help further embed the knowledge being taught.
We have worksheets for the following physics equations:
Paper 1:
Energy
Kinetic Energy = 0.5 x Mass x (Speed)2)
Elastic Potential Energy = 0.5 x Spring Constant x (Extension)2
Gravitational Potential Energy = Mass x Gravitational Field Strength x Height
Change in Thermal Energy = Mass x Specific Heat Capacity x Temperature Change
Efficiency calculation
Power = Energy Transferred / Time
Power = Work Done / Time
Electricity
Charge Flow = Current x Time
Potential Difference = Current x Resistance
Power = Potential Difference x Current
Power = (Current)2 x Resistance
Energy Transferred = Charge Flow x Potential Difference
Particle Model of Matter
Density = Mass / Volume
Energy for a Change of State = Mass x SLH
Paper 2:
Forces
Weight = Mass x Gravitational Field Strength
Force = Spring Constant x Extension
Speed = Distance / Time
Acceleration = Change in Velocity / Time
Resultant Force = Mass x Acceleration
Work Done = Force x Distance
Momentum = Mass x Velocity
Waves
Period of a Wave = 1 / Frequency
Wavespeed = Frequency x Wavelength
Magnetism
Force = Magnetic Flux Density x Current X Length
