The light turns green, the driver steps on the gas, and the car accelerates from rest.
This situation can best be described as a transformation of
Kinetic energy into Chemical energy
Chemical energy into Dissipated energy (eg., heat)
Chemical energy into Kinetic energy
Dissipated energy (eg.. heat) into Kinetic energy
Potential energy into Kinetic energy

The force is push or pull

Electricity and discharge

Distance covered = speed x timethe distance traveled going against the stream = distance traveled with the stream.therefore it is the speed and the time that are the variables.as he travels the same distance both ways, speed x time is the same for each way.going upstream his speed is 4 kph; going downstream his speed is 6 kph.therefore we have two simultaneous equations: time upstream x 4 = time downstream x 6time upstream + time downstream = 60 minutestherefore we have the equation: time upstream = 6/10 hour, time downstream therefore = 4/10 hour.distance traveled at 4km/hr in 6/10 hour = 24/10 = 2.4km.check: distance traveled at 6km/hr in 4/10 hour = 24/10 = 2.4km.
