1
Q

Distance travelled =

A

Average speed x time

X = s x t

2
Q

Acceleration =

A

Change in velocity ➗ time

A = (V-U) ➗ t

3
Q

Force=

A

Mass x acceleration

F = M x a

4
Q

Weight=

A

Mass x gravitational field strength

W = M x g (10)

5
Q

Momentum =

A

Mass x velocity

P = M x v

6
Q

A change in gravitational energy =

A

Mass x gravitational field strength x change in vertical height

^GPE = M x 10 x ^h

7
Q

Kinetic energy =

A

0.5 x mass x speed squared

KE = 0.5 x m x v2

8
Q

Efficiency =

A

Useful energy transferred ➗ total energy supplied to device

9
Q

Wave speed =

A

Frequency x wavelength

V = F* x h*

     OR

Distance➗time

V = X ➗ T

10
Q

Work done =

A

Force x distance moved in direction of the force

E = F x D

11
Q

Power =

A

Work done ➗ time taken

       OR

Energy transferred ➗ time taken

Both

P= E ➗ T

12
Q

Energy transferred =

A

Charge moved x potential difference

E = Q x V

13
Q

Charge =

A

Current x time

Q = I x T

14
Q

Potential difference =

A

Current x resistance

V = I x R

15
Q

Electrical power =

A

Current x potential difference

P = I x V

       OR

Current squared x resistance

P = I2 x R
