Paper 1 Equations Flashcards
1
Q
Work Done Equation
A
Work Done = Force x Distance
2
Q
Energy Equation
A
Energy = Power x Time E = P x t
3
Q
Efficiency Equation ( Energy )
A
Efficiency = Useful Energy/Input Energy
4
Q
Efficiency Equation ( Power )
A
Efficiency = Useful Energy/Input Energy
5
Q
Kinetic Energy Equation
A
Kinetic Energy = ½ x Mass x Velocity²
E(k) = ½ x m x V
6
Q
Gravitational Potential Energy Equation ( GPE )
A
GPE = Mass x Gravitational Field Strength x Height
7
Q
Density Equation
A
Density = mass/Volume p = m/V
7
Q
Potential Difference/Voltage Equation
A
Voltage = Current x Resistance V = I x R
8
Q
Power Equation
A
Power = Current x Voltage P = I x V
Or
Power = Current² x Resistance P = I² x R
9
Q
Charge Equation
A
Charge = current x time Q = I x t
10
Q
Power Equations (both time)
A
Power = energy transferred/time P = E/t
Or
Power = Work Done/time P = W/t
11
Q
Energy Equation (Includes V)
A
Energy = Charge x Potential Difference E = Q x V
