1
Q

Write down the equation that links Weight, mass and Gravitational
field strength?

A

Weight = mass x gravitational field strength (g)

2
Q

Write down the equation that links
work done, force and distance
(along the line of action of the
force)

A

Work done = force x distance (along the line of action of the force)

3
Q

Write down the equation that links
Force applied to a spring, the
spring constant and the extension?

A

Force applied to a spring = spring constant x extension

4
Q

Write down the equation that links distance travelled, speed and time?

A

Distance travelled = speed x time

5
Q

Write down the equation that links

Acceleration, change in velocity and time taken?

A

Acceleration = change in velocity / time taken

6
Q

Write down the equation that links resultant force, mass and acceleration?

A

Resultant force = mass x acceleration

7
Q

Write down the equation that links

momentum, mass and velocity?

A

Momentum = mass x velocity

8
Q

Write down the equation for kinetic energy?

A

Kinetic energy = 0.5 x mass x (mass)2

9
Q

Write down the equation that links

Gravitational potential energy, gravitational field strength, mass and height?

A

Gravitational potential energy = mass x gravitational field strength (g) x height

10
Q

Write down the equation that links power, energy transferred and
time?

A

Power = energy transferred / time

11
Q

Write down the equation that links

power, work done and time?

A

Power = work done / time

12
Q

Write down the equation that links energy transferred, power and time?

A

Energy transferred = power x time

13
Q

Write down the equation for efficiency?

A

There are two!

Efficiency = useful output energy transfer / total input energy transfer

Efficiency = useful power output / total power input

14
Q

Write down the equation that links

wave speed, frequency and wavelength?

A

Wave speed = frequency x wavelength

15
Q

What is the equation for density
when you are given the mass and
volume?

A

Density = mass / volume

16
Q

Write down the equation that links

Charge, current and time?

A

Charge flow = current x time

17
Q
Write down the equation that links 
potential difference (voltage), 
resistance and current?
A

Potential difference = current x resistence

18
Q

Write down the equation that links
power, potential difference and
current?

A

Power = potential difference x current

19
Q

Write down the equation that links

power, current and resistance?

A

Power = (current)2 x resistence

20
Q
Write down the equation that links
Energy transferred, charge and 
potential difference (voltage)?
A

Energy transferred = charge flow x potential difference

21
Q

TRIPLE SCIENCE: Write down the equation that links
Moment, force and distance
(normal to direction of force)?

A

Movement = force x distance

22
Q

TRIPLE SCIENCE: Write down the equation that links pressure, force and area?

A

Pressure = force normal to a surface / area of that surface
