Physics resources for IGCSE or GCSE students.
Revision sheets for IGCSE or GCSE physics.
The idea is read the information and than print the quiz sheet and try the questions.
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.
