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

11

What symbol often represents acceleration due to gravity?

g
