Mechanics
Work & Energy
Track energy: work, kinetic, potential, power
4 skills · Last skill is Premium
Work and energy track how forces change motion over a distance. Practice work at an angle, kinetic and potential energy, conservation with and without friction, and power in watts.
Skills in this topic
Work
Find the work a force does, at an angle to the motion and against friction
Kinetic & Potential Energy
Compute kinetic and gravitational potential energy, and work back to speed or height
Conservation of Energy
Trade height for speed on a frictionless path, and account for what friction takes
Power
Relate work, time, force and speed through power, measured in watts

Understanding Work and Energy Intuitively (The Bookkeeping Shortcut)
Work is force times distance, energy is the ledger it fills, and conservation is the ledger balancing. Kinetic, potential, friction, power, when to skip Newton.
