1

What is the equation that links weight, mass and gravity?

weight = mass × gravitational field strength (g)

W=M x G

2

What equation links work done, force and distance.

work done = force × distance
along the line of action of the force

W=Fs

3

What equation links force spring constant and extension

force applied to a spring = spring constant × extension

F=Ke

4

What equation links distance, speed and time?

distance travelled = speed × time
S= D x T

5

What equation links acceleration velocity and time.

acceleration =
change in velocity
time taken

A=§V/T

6

What links resultant force with mass and acceleration

resultant force = mass × acceleration
F=MxA

7

What equation links momentum, mass and velocity.

momentum = mass × velocity
P= MxV

8

What links kinetic energy, 0.5 mass and speed.

kinetic energy = 0.5 × mass × speed
2

9

What links gravity mass and height?

gravitational potential energy = mass
× gravitational field strength g × height

10

What links power and energy transfered.

power =
energy transferred
time

11

What links power, work done and time

power =
work done
time

12

What is equation to find efficiency.

efficiency =
useful output energy transfer
total input energy transfer

13

What is the efficiency equation

efficiency =
useful power output
total power input

14

What is wavespeed equation?

wave speed = frequency × wavelength

15

What is charge flow equation?

charge flow = current × time
