Build motion experiments with trolleys, slopes and a 2D collision table. Measure with light gates, explore forces and momentum, and compare recorded runs.
Learning guide and suggested activities
What this tool shows
How mass, applied force and friction affect acceleration
Motion on horizontal tracks, inclined tracks and ramps
Elastic, inelastic and sticking collisions in one and two dimensions
Light-gate timing and the difference between model values and instrument readings
Momentum components, collision impulse and kinetic energy before and after impact
OCR A relevance
Forces and motion: kinematics, force components, Newton’s laws, momentum and energy
Practical skills: measurements, graphs and comparing experimental runs
AQA relevance
GCSE forces: motion, resultant force, acceleration and momentum
A-level mechanics: vectors, motion, forces, energy and momentum
Try these tasks
Measure the speed of a trolley using a timing flag and two light gates.
Double the mass while keeping the applied force constant. Compare velocity–time graphs.
Change the track angle and surface. Predict the acceleration and stopping distance.
Compare momentum and kinetic energy when two trolleys stick together.
Use the collision table to check momentum conservation in perpendicular directions.
