Forces covers Forces and their interactions, Work done and energy transfer, Forces and elasticity, and Forces and motion in GCSE AQA Foundation Combined Science Physics. 24 lessons in 4 subtopics.
Distance is calculated with s = vt, distance = speed × time. The Distance, Displacement and Speed (Part 2/3) notes cover this in full.
Typical speeds are about 1.5 m/s for walking, 3 m/s for running and 6 m/s for cycling. The Distance, Displacement and Speed (Part 1/3) notes cover this in full.
Newton's Second Law states that the acceleration of an object is proportional to the resultant force acting on it and inversely proportional to its mass. The Newton's Second Law: F = ma (Part 1/2) notes cover this in full.
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 equation for acceleration is a = Δv/t, where Δv is the change in velocity (final velocity − initial velocity) in m/s and t is the time taken in s. The Acceleration, Velocity-Time Graphs and Terminal Velocity (Part 1/3) notes cover this in full.
Newton's Third Law states that whenever two objects interact, the forces they exert on each other are equal in magnitude and opposite in direction. The Newton's Third Law: Action and Reaction notes cover this in full.
Velocity is the speed of an object in a given direction, measured in metres per second (m/s) in a specified direction. The Distance, Displacement and Speed (Part 3/3) notes cover this in full.
Inertia is the tendency of objects to continue in their state of rest or of uniform motion, so objects 'resist' changes to their motion. The Newton's First Law of Motion notes cover this in full.
