AQA GCSE Combined Science: Trilogy physics topics overview quiz quiz

Kinetic energy equals one half times mass times speed squared

Kinetic energy equals mass times speed

Kinetic energy equals mass times gravitational field strength times height

Kinetic energy equals force times distance

Energy is gradually used up and disappears completely over a long time

Energy cannot be created or destroyed, only transferred, stored or dissipated

Energy can be created from nothing inside a large modern electrical power station

Energy is permanently destroyed by friction between two moving surfaces

V equals I divided by R

V equals R divided by I

V equals I times R

V equals I plus R

The pressure decreases because the gas particles slow right down and hit the container walls less

The pressure stays exactly the same because the volume of the gas is held fixed

The gas immediately turns into a liquid as it is heated up inside the container

The pressure increases because particles move faster and hit the walls harder and more often

Alpha radiation

Gamma radiation

Beta radiation

Ultraviolet radiation

The time taken for all of the unstable nuclei in the sample to decay

The time for half the unstable nuclei (or the count rate) to decay

Half of the total age of the radioactive sample being measured

The time taken for the sample to double its activity and count rate

Weight equals mass divided by gravitational field strength

Weight equals mass times acceleration of the car

Weight equals mass times gravitational field strength

Weight equals force times distance

Braking distance and skid distance

Reaction distance and engine distance

Acceleration distance and braking distance

Thinking distance and braking distance

Wave speed equals frequency times wavelength

Wave speed equals frequency divided by wavelength

Wave speed equals wavelength divided by frequency

Wave speed equals amplitude times frequency

The size of the current flowing in the wire

The magnetic field, from north to south

The force or the direction of motion of the wire

The total resistance of the whole circuit
