## Acceleration

the rate at which a body increases in velocity

.e.g.

change in velocity

time taken

1 of 19

## Action

a pushing or pulling force that acts on an object

2 of 19

## Collision

an impact between two or more objects

3 of 19

## Displacment

distance covered in a certain direction

4 of 19

## Force

pushing or pulling action which results in an object moving, accelerating, changing direction, or remainnig stationar, given by mass x acceleration mraured in newtons

5 of 19

a measure of how steep a line or slope is, can be positive or negative

6 of 19

## Magnitude

a measurement of size

7 of 19

## Momentum

a measure of state of motion of an objects given but

mass x velocity

(a vector quantity) measured in kg m/s

8 of 19

## Reaction

a force that is equal in size but opposire in direction to an action

9 of 19

## Resistance

a force that opposes motion

10 of 19

## Resultant Force

the total force acting on an object

11 of 19

## Risk

a perceived measure of the probability of something happening

12 of 19

## Speed

the rate at which the body moves

distance

time taken

13 of 19

## Stopping Distance

how long it take a vehical to stop,

the sum of thinking distance and the braking distance

14 of 19

## Vector

a quantity that had both magnitude(size) and direction

15 of 19

## Velocity

the speed at which an abject moved in a particular direction

displacment

time taken

16 of 19

## Velocity - Time - Graph

represents acceleration (velocity again time taken)

17 of 19

## Weight

the vertical force of an object, the product of mass and gravitational feild strength; measured in newtons

18 of 19

## Terminal Velicity

the constant velocity reached by a falling body
