Formula highlights
Distance
distance = speed x time
Power
P = W / t
Motion basics
Distance, speed, and time stay reliable when units are consistent and the interpretation of average speed is kept clear.
Work and energy
Work describes transferred energy in simple aligned-force cases. Energy quantities describe stored or moving capacity for change.
Power as rate
Power turns work or energy into a rate question. Without time, you do not yet have power.
Worked examples
Convert minutes to seconds before combining with m/s.
Compare how changing speed affects kinetic energy much more strongly than it affects momentum.
Common mistakes
- Mixing units across motion calculations.
- Confusing energy with power.
- Using average-rate formulas in settings that need a more detailed motion model.
