Explain whya horse cannot pull a cart and run in empty space

Answer»

Solution :While TRYING to pull a cart , a horse pushes the ground backwards with a certain force at an ANGLE . The ground offeres an equal reaction in the opposite DIRECTION , on the horse . The FORWARD COMPONENT of this reacion is responsible for motion of the cart . In empty space , there is no reaction and hence , a horse cannot pull the cart and run .
