Flashcards in FM1 - Velocity and acceleration Deck (21):

1

## What do speed and velocity both show and what are they measured in?

###
How fast an object is going

m/s

2

## What is the difference between speed and velocity?

### Velocity shows how fast your going as well as the direction it is going in

3

## What is the equation for average speed?

### Average speed = distance/time

4

## What is the triangle formula?

### D/s x t

6

## What is acceleration?

### How quickly velocity changes

7

## What can the change in velocity be?

### Change in speed or change in direction

8

## What is the formula and unit for acceleration?

###
Acceleration = Change in velocity/ time taken

m/s2 (squared)

9

## On a distance time graph, what does the gradient represent?

### Speed - the steeper the diagonal line, the faster it is going

10

## On a distance time graph, what does a flat line represent?

### Where it has stopped

11

## On a distance time graph, what do curves represent?

### Acceleration or deceleration

12

## On a distance time graph, a steepening curve means?

### Its speeding up (increasing gradient)

13

## On a distance time graph, a levelling off curve means?

### Its slowing down (decreasing gradient)

14

## On a distance time graph, what does a downhill section represent?

### Going back to the starting point

15

## On a velocity time graph, the gradient represents what?

### Acceleration

16

## On a velocity time graph, a flag section/line represents?

### A steady speed

17

## On a velocity time graph, the steeper the graph...

### The greater the acceleration/ deceleration

18

## On a velocity time graph, uphill sections (/) are?

### Acceleration

19

## On a velocity time graph, downhill sections (\) are?

### Deceleration

20

## On a velocity time graph, what does a curve represent?

### Changing acceleration

21

## Can you work out the total distance traveled on a velocity time graph?

### Yes - the are under any section of the graph is equal to the distance travelled in that time taken
