Have a nucleus containing protons and neutrons
Electrons surround the nucleus
Atom has no overall charge

Electrostatic charges:
Insulating materials can be given an electrostatic charge by rubbing two materials together.
Electrons are transferred from one material to another. The material that has gained electrons has
a negative charge and…

The current in a circuit is measured using an ammeter.
The voltage is measured using a voltmeter .

1 volt = 1 joule per coulomb

If the voltage is increased, the current increases, if it is decreased, the current decreases.

Resistance, Current and voltage

Resistance is a way of measuring…

Distance ­ path/route taken
Displacement ­ distance in a straight line from start to finish

Distance-time graphs:
Gradient = speed
Speed is always positive
Velocity can be positive or negative

distance travelled in a certain direction(m)
Velocity(m/s) = time taken(s)




Velocity and Acceleration

Acceleration:
Is a change in velocity
Is…

Force(N) = mass(kg) × acceleration(m/s2 )


Terminal Velocity

Calculating weight:
The gravitational field strength on
Earth is 10N
Mass must always be in kilograms

Weight(N) = mass(kg) × gravitational field
strength(N/kg)

W=m×g

Mass ­ quantity of matter (doesn't
change)
Weight ­ measure of the pull of gravity
on an object…

Are you going to put the other topics that arent highlighted in purple?

Littleone

What about the other topics that are not highlighted in purple?

Amshungryfoodlover

The ones highlighted in purple werent included because it was part of GCSE science, not additional science.
