Flashcards in Equations Deck (22):

1

## Weight

### Weight = mass x gravitational field strength

2

## Work done

### Work done =force x distance

3

## Force applied to a spring

###
Force applied to a spring = spring constant x extention

4

## Moment

### Moment = force x distance

5

##
Pressure

### Pressure = force / area

6

## Distance traveled

### Distance traveled = speed x time

7

## Accelaration

### Accelaration = change in velocity / time taken

8

## Resultant force

### Resultant force = mass x acceleration

9

## Momentum

### Momentum = mass x velocity

10

## Kinetic energy

### Kinetic energy = 0.5 x mass x velocity squared

11

## Gravitational potential energy

### Gravitational potential energy = gravitational field strength x height x mass

12

## Power (energy)

### Power = Energy transferred / time

13

## Power (work)

### Power = work done / time

14

## Efficiency

### Efficiency = useful output / total input

15

## Wave speed

### Wave speed = frequency x wavelength

16

## Charge flow

### Charge flow = current x time

17

## Potential difference

### Potential difference = current x resistance

18

## Power (circuits)

### Power = potential difference x current

19

## Power (circuits without voltage)

### Power = resistance x current squared

20

## Energy transferred

### Energy transferred = power x time

21

## Energy transferred (circuits)

### Energy transferred = charge flow x potential difference
