It is easier to lift a small stone but harder to lift heavy one on the surface of earth. Why?
Answers
Answer:
bcz of the mass of the larger stone requires more energy to lift it to a certain height as G.P.E ∝ mass of an object
Answer:
A large stone is more challenging to lift than a little stone. Bigger forces are needed to move larger amounts of mass because larger stones have more mass than smaller stones. Since mass determines the strength of the gravitational field, objects with higher mass are subject to a greater gravitational pull.
Explanation:
It is because, as we all know, a huge stone's mass is frequently more than a smaller stone. The influence of the earth's attraction on a larger stone can be seen more clearly than the effect of the earth's attraction on a smaller stone. Therefore, on the earth's surface, it is more difficult to lift a large stone than a smaller one.
A large stone is heavier than a little one. Additionally, mass and weight are directly proportionate, with g being a constant for all objects on earth. Larger stones therefore weigh more than smaller ones. Because of this, it is more difficult to lift larger stones on the earth's surface than to lift smaller ones.
Considering that g is constant on the same surface, W ∝ m. Therefore, more power must be used to overcome a greater mass. As a result, on the earth's surface, it is more difficult to lift a large stone than a smaller one.
