Why the force needed to start a cart,is (somewhat) greater than the force needed to keep it moving with a uniform speed?
Answers
The force required to start the car is greater than the force required to run it at uniform speed because it needs to overcome static inertia and friction.
A body remains stationery unless an outside force affects it and it remains running unless it is stopped.
However, when the cart is in motion, it experiences inertia of motion (which keeps the cart in motion) and sliding friction (which is less than static friction).
