Flashcards in Equations complete Deck (15):

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
