Forces covers Forces and their interactions, Work done and energy transfer, Forces and elasticity, and Moments, levers and gears (physics only) in GCSE AQA Foundation Physics. 23 lessons in 7 subtopics.
The formula for work done is W = F × d: work done in joules equals force in newtons times distance moved in metres. The Introducing Work Done notes cover this in full.
The formula for pressure is p = F/A: pressure in pascals (Pa) equals the force normal to a surface in newtons divided by the area in m². The Understanding Pressure in Fluids notes cover this in full.
Archimedes' principle states that the upthrust on an object equals the weight of fluid displaced by the object. The Upthrust, Floating and Sinking notes cover this in full.
The momentum formula is p = mv: momentum (kg m/s) = mass (kg) × velocity (m/s). The Understanding Momentum notes cover this in full.
The unit of momentum is kg m/s, because momentum is mass in kg × velocity in m/s. The Understanding Momentum notes cover this in full.
A force is a push or pull that acts on an object due to the interaction with another object, measured in newtons (N). The Introduction to Contact and Non-Contact Forces notes cover this in full.
Mass is the amount of matter in an object, measured in kilograms (kg), and it is the same everywhere. The Introduction to Gravity and Weight notes cover this in full.
The formula for weight is W = mg: weight in newtons (N) equals mass in kilograms (kg) times gravitational field strength in newtons per kilogram (N/kg). The Calculating Weight Using W = mg notes cover this in full.
