1

## Acceleration meaning?

### A change in velocity

2

## Is acceleration a scalar or a vector?

### Vector

3

## What is the units of acceleration?

### Meters per second squared

4

## What does an acceleration of 10m/s mean?

### Each second the velocity increases by 10m/s

5

## What is the formula linking acceleration, velocity and time?

### Acceleration = change in velocity / time taken

6

## What if an object accelerates but gets slower?

### It’s called deceleration and will be a negative value

7

## What formula relates final velocity, initial velocity, acceleration and distance travelled?

###
(Final velocity)^2 - (initial velocity)^2 = 2 x acceleration - distance

Can also be written:

x= v^2 - u^2 / 2 x a

8

##
a = (v - u)/t

What does each letter stand for?

###
a = acceleration

v = final velocity

u = initial velocity

t = time taken for velocity to change

9

## Why does an object in free fall move downwards?

### Due to the force of gravity acting upon it

10

## What’s acceleration due to gravity?

### Constant 9.8 m/s^2 but can often be rounded to 10 m/s^2
