Motion, Work, and Energy Revision Pack
A better revision pack for motion, work, energy, and power, with worked examples and rate-versus-quantity reminders.
A fuller mechanics sheet covering force, work, power, momentum, and energy with unit discipline and interpretation reminders.
Use this pack as a quick way to keep the main mechanics quantities connected: force changes motion, work transfers energy, power describes rate, and momentum and energy capture different aspects of motion.
500 J of work in 10 s corresponds to 50 W average power.
Doubling speed quadruples kinetic energy for the same mass.
Calculate force from mass and acceleration using Newton's second law.
Calculate work from force and distance when the force acts through the displacement in the direction of motion.
Use the Kinetic Energy Calculator to solve kinetic energy from a standard physics relationship with explicit units.
Use the Potential Energy Calculator to solve potential energy from a standard physics relationship with explicit units.
Use the Momentum Calculator to solve momentum from a standard physics relationship with explicit units.
Use the Distance Calculator to solve distance from a standard physics relationship with explicit units.
Use the Speed Calculator to solve speed from a standard physics relationship with explicit units.
Use the Time Calculator to solve time from a standard physics relationship with explicit units.
Use the Gravitational Force Calculator to solve gravitational force from a standard physics relationship with explicit units.
A fuller mechanics reference covering force, work, power, momentum, kinetic energy, and potential energy, with a strong emphasis on units, interpretation, and when each relationship is the right one to use.
A stronger guide to distance, speed, and time relationships, built around unit consistency, average-rate thinking, and the practical limits of the simple triangle model.
A fuller guide to gravitational force, explaining inverse-square behaviour, centre-to-centre separation, and the difference between mass, weight, and interaction force.
