A bench for secondary physics
Work the example, then run the practical.
Nine topics, from motion to pressure. Each one has a worked example you open step by step, short checks with the reason, and a bench that uses the same equation.
- Examples
- 0/18
- Checks
- 0/36
- Practicals
- 0/11
Contents
All topicsMechanics
How things move, and why the motion changes.
Waves and light
Oscillations, sound, and rays.
Matter and heat
Particles, heating, density, and pressure.
On the bench
All practicals- v = u + atMotion trackCheck the constant-acceleration equations against a timed run.
- a = F / mForce trolleySee that acceleration depends on the resultant force and the mass.
- k = F / xSpring balanceMeasure a spring constant from the extension caused by a known weight.
- mgh = (1/2)mv²Drop towerWatch gravitational energy become kinetic energy as a mass falls.
How a mark is won
- Write the formula before you put numbers in.
- Convert to metres, kilograms, and seconds.
- Substitute, then evaluate.
- Ask whether the size and the unit make sense.
A set of mixed checks
Eight questions drawn from the whole course. Wrong ones point you back at the topic, with the working still there.
