Flashcards in Distance, Speed, Velocity & Acceleation graphs Deck (14):

1

## What are vectors?

### Quantities that have a magnitude (size) and direction.

2

## What are scalars?

### Quantities with only a magnitude.

3

## What is displacement?

### Measures the distance and direction in a straight line from objects starting point to finishing point. (Vector quantity).

4

## What is velocity?

### Speed in a given direction.

5

## What is speed?

### How fast you are going with no regard to the direction.

6

## What is distance?

### How far an object has moved. (Scalar)

7

## What is acceleration?

### How quickly You're speeding up. (Vector)

8

## What is the formula for distance?

### Speed x time

9

## What is the formula for acceleration?

###
(f-i) (change in velocity)

------

time

10

## What is the formula for uniform acceleration?

### v2 - u2 = 2 x a x d

11

## What is the speed on a distance time graph?

### speed=gradient=change in the vertical/change in the horizontal

12

## What are the different parts of a distance time graph?

###
+ The gradient - gives the speed of an object

+ Flat - object has stopped

+ A steeper graph - object is going faster

+ Curves - represent acceleration

+ Curve getting steeper - object is speeding up

+ Levelling off - slowing down (decreasing gradient)

13

## What are the different parts of a velocity/time graph?

###
+ Gradient = acceleration

+ Flat - steady speed

+ Steeper the graph - greater the acceleration or deceleration

+ Uphill (/) - acceleration

+ Downhill (\) - deceleration

+ Curve - changing acceleration
