A Level Maths 9709 Paper 4 lectures
Mechanics. 14 short lectures, one for each part of the syllabus, in the order it is taught. Each one teaches a topic on the board in a few minutes. The teaching part is free to watch; a free account opens the rest of every lecture: worked examples, practice questions and real past-paper questions answered.
Chapter 4.1 Forces and equilibrium
Chapter 4.2 Kinematics of motion in a straight line
- Constant acceleration, vertical motion and velocity-time graphsA bus pulls away, cruises, then brakes.5 min
- Acceleration and displacement as functions of time, and displacement-time graphsDisplacement, velocity, acceleration: each one is the rate of change of the one before.6 min
- Variable acceleration in stages and velocity as a function of timeSometimes one formula cannot describe the whole journey.6 min
- Two particles: gravity, a track, successive intervals and mid-air collisionsTwo particles, one story.7 min
Chapter 4.3 Momentum
Chapter 4.4 Newton's laws of motion
- Particles connected by a string, over a pulley, and with a planeTwo particles joined by a light string.6 min
- A car against a resistance, and motion on rough and smooth inclined planesA minibus on a flat road.6 min
- A vehicle towing a trailer, vertical motion against a resistance, and a liftA car towing a caravan.6 min
Chapter 4.5 Energy, work and power
- Friction, Newton’s second law and power on a horizontal roadDrag a heavy block along the ground and you feel it resist.6 min
- Work, energy and power: average power, slopes and variable resistanceA car engine burns fuel and the car speeds up.6 min
- Work and energy on curves, connected particles and rough planesNewton's second law gives you accelerations, and then you need the suvat equations to get speeds.6 min
- Work and energy on slopes, with an engine and with frictionYou could solve a slope problem with forces and suvat.6 min
