Equations

Question 1

Work done equation

Answer 1

Fx (force x distance)

Question 2

Ek(kinetic energy)

Answer 2

1/2 mv^2 (0.5 x mass x velocity squared)

Question 3

Ep(gravitational potential)

Answer 3

Mgh (mass x gravity x change in height)

Question 4

Work done when force is at an angle

Answer 4

Wd =fx x cos (theta)

Question 5

V (electricity)

Answer 5

V= IR

Question 6

Voltage across circuit (electricity)

Answer 6

I total = I1 + I2 + I3 +…

Question 7

Finding resistance in a circuit

Answer 7

1/R total = 1/R1 + 1/R2 + 1/R3 +…

Question 8

Emf (electricity)

Answer 8

Electromagnetic force = V1+V2. (Product of total resistance and current of the circuit)

Question 9

I (electric current)

Answer 9

I=Q/t (Current = Charge/ Time)

Question 10

V (potential difference - electricity)

Answer 10

V= W/Q (voltage = energy transferred/ charge)
Energy transferred between two points in a circuit.

Question 11

All of voltages links to other equations

Answer 11

V=W/Q = E/Q
