Energy Equations Physics Gcse. E = i × v × t. Energy efficiency (%) = (useful energy out ÷ total energy in) x 100.
A quiz to see how well you know the equations you have to memorise for gcse physics. E is the energy transferred in joules, j. If you're taking gcse (9—1) combined science or gcse (9—1) physics, you need to know these equations:
E = I × V × T.
A quiz to see how well you know the equations you have to memorise for gcse physics. I is the current in amperes, a. Additional gcse science physics equations.
These Are Perfect For Students To Work Through In Lessons Or Independently At Home.
Units used (kwh) = power (kw) time (h) Efficiency (%) = (useful energy out ÷ total energy in) x 100. E = v x i x t energy = voltage x current x time.
Worksheets To Support All Areas Of Gcse Physics!
A cold spoon is dropped into an insulated flask of hot soup and then sealed, energys transferred from thermal enegry store of the soup to the useless. Click on an equation below for more information. Kinetic energy = 0·5 x mass x.
Conservation And Dissipation Of Energy.
Energy = current x voltage x time. This is a standard format for. It also includes a mindmap for the gcse energy topic with blanks and a teachers answer sheet.
Gravitational Potential Energy = Mass × Gravitational Field Strength × Height𝐸p =M G H.
Energy transfers and the national grid, including recalling and applying equations for power. P = e ÷ t power = energy ÷ time. Energy equations to learn kinetic energy = 1 2 × mass × 2speed2 e k = 1 2 mv gpe = mass × gravitational field strength × height 𝑃= ℎ power = work done time taken = energy transferred time taken = = efficiency = useful energy output total energy input efficiency = useful power output total power input equations given in the exam
