Is it easier to push or pull weight?
Pulling is easier if you are taller than the object. Otherwise pushing would be easier. When you pull an object smaller than you, a part of the force we apply acts upward and reduces the weight of the object. But if you push, the vertical component of your force increases the weight and makes it tough.
