A horse has to apply more force to start a cart than to keep it moving. Why? |
| Answer» When the horse is applying force to start the cart it has to overcome static friction and to keep the cart in motion,the horse has to overcome sliding friction. But static friction is more than sliding friction ,so the horse, pulling a cart has to apply a greater force to start the cart than to keep the cart in motion. | |
