Physics resources for IGCSE or GCSE students.

Revision sheets for IGCSE or GCSE physics.
This series revision sheets are based on the IGCSE & GCSE syllabuses.
Lots of formulas, definitions and key points to learn off.
There are also accompanying test sheets to check your memorisation.

The idea is read the information and than print the quiz sheet and try the questions.

 Revision Exercise one: Forces and Motion unit of Distance: m, "metre". unit of time: s, "second" Speed = Distance ÷ Time Velocity is speed in a certain direction. Velocity = Distance ÷ Time unit of Velocity: m/s, "metres per second" Acceleration: a change in velocity.
 Acceleration = Change in Velocity ÷ Time. a = (v-u) ÷ t             a = acceleration             v = final velocity             u = initial velocity             t = time unit of acceleration: , "metres per second squared"  Distance is the area under the velocity time graph. Newtons laws 1) Velocity remains constant unless acted on by a resultant force Issac Newton

2) Force = mass x acceleration

F = m x a

3) If A applies a force to B, B applies an equal but opposite force on A

Unit of force: N, "Newton"  N=kg

Mass (m) is an amount of substance. Unit kg "kilograms".

Gravity is a force of attraction between masses.

The acceleration due to gravity on earth (g) is aprox. 10 m/s2

Weight (W) is the force of gravity pulling on a mass.

W = mg

Friction is a force that opposes motion due to passing objects rubbing off each other.

Density = mass ÷ volume

= m ÷ v

Put your hand on a hot stove for a minute, and it seems like an hour. Sit with a pretty girl for an hour, and it seems like a minute. That's relativity.
