A horse pulling a cart has to apply a greater force to start the cart than to keep the cart in motion Why ?

Text Solution

Verified by Experts

To start the cart inertia of rest (of the cart) has to be overcome Further force required to be applied has to be greater than the force of limiting friction Once the motion starts force of kinetic friction has to be overcome , which is less than the force of limitting friction Hence smaller force is enough to keep the cart in motion .
