Speed in a specified direction.

1

A flat line on this type of graph means stationary.

2

Measured in m/s/s (m/s2) or (ms-2).

3

Change in velocityTime taken

4

‘Amount of stuff’, this remains constant even if you’re on the

moon!

5

The size difference between 2 opposite forces. This determines

any changes in movement.

6

The size of a resultant force required to produce no change

in movement.

7

The maximum speed an object can reach. This can be changed

by producing a non-zero resultant force (often by

increasing / reducing the resistance).

8

This is affected by:Your speed

Tiredness, distractions, poor visibility, alcohol, carelessness,

drugs, answering your phone etc.

9

The higher you are, the more you have.

Mass x gravity x height

10

The faster you go, the more you have.

½ x mass x velocity2

11

Kids Hate Learning GCSEEnergy Names.

12

Energy cannot be created or destroyed, only transferred into

other types.

13

The extension of an elastic object in relation to the force

applied (until the elastic limit of proportionality is reached).

14

Also known as Energy Transferred.

Measured in J or Nm

15

Momentum before compared with momentum after.

16

Opposite charges _______.

17

Voltmeters are connected like this so they can measure the difference in energy across a

component.

18

This has a constant current, wherever it is measured.

19

The average time for the number of nuclei in a

radioactive sample to halve .
