Flashcards in Equations Deck (11):

1

##
weight = mass × gravitational field strength g

### W=mg

2

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

### W=Fs

3

## Force applied to a spring = spring constant × extension

### F=ke

4

## distance travelled = speed × time

### S = vt

5

## acceleration = change in velocity / time taken

### a=∆v / t

6

## Resultant force = mass × acceleration

### F=ma

7

## momentum = mass × velocity

### P = mv

8

## kinetic energy = 0.5 × mass × speed 2

### E k = 1/2 m v 2

9

##
gravitational potential energy = mass

× gravitational field strength g × height

### Ep = m g h

10

## power= energy transferred / time

### P = Et
