Acceleration
The amount by which speed increases in one second.
1 of 21
Atmospheric Pressure
Pressure caused by the collisions of air molecules that produce a force.
2 of 21
Average Speed
The total distance travelled in the total time taken for a complete journey.
3 of 21
Centre Of Gravity
The point in an object where the force of gravity seems to act.
4 of 21
Centre Of Mass
The point in an object where the mass of an object seems to act.
5 of 21
Compressed
Squashed into a smaller space.
6 of 21
Density
The mass of a material in a certain volume.
7 of 21
Distance-Time Graph
A graph that shows how far an object moves each second.
8 of 21
Gas Pressure
The force exerted (applied) by air particles when they collide with a surface.
9 of 21
Incompressible
Cannot be compressed (squashed).
10 of 21
Instantaneous Speed
The speed at a particular moment.
11 of 21
Law Of Moments
The object is in equilibrium (balanced) if the clockwise moments equal the anti-clockwise moments.
12 of 21
Liquid Pressure
The pressure produced by collisions of particles in a liquid.

Pivot
The point about which a lever or see-saw balances.
18 of 21
Pressure
A forced exerted (applied) on a certain area.
19 of 21
Relative Motion
The difference between the speeds of 2 moving objects, or of a moving and stationary object.
