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

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 .
