Power Watts W
Work Joules J
Frequency Hertz Hz
Time Seconds S
Resistance Ohms Ω

3. Now try these Acceleration Specific latent heat Specific heat capacity
Momentum
Density
Velocity (speed)

4. Answers Acceleration m/s2 Specific latent heat J/kg
Specific heat capacity J/kg/oC
Momentum Ns
Density kg/m3
Velocity (speed) m/s

5. Give the word equations to find the following
Weight
Wave speed
Potential difference
Energy transferred
Density
Magnification
Distance travelled

6. Answers Weight = mass x gravitational field strength
Wave speed = frequency x wavelength
Potential difference = current x resistance
Energy transferred = power x time
Density = mass/volume
Magnification = image height/object height
Distance travelled = speed x time
