Power of an engine: P = Fv, top speed and acceleration

A car with engine power P fights drag, rolling resistance and slope; see F = P/v, the acceleration curve and the top speed.

About this experiment

What you do in the lab

Change the controls and watch the physics behave in real time in 3D. Live readouts and graphs show the numbers behind it, and the Learn tab has the theory, procedure, observations and viva questions. Works on a phone or a laptop, in English and Hindi.

Topics: power · P=Fv · drag · top speed
