1. Robin carries the trash from the house to the garbage can outside. Which statement best describes the science of what he did? He would use less energy if he were to move the garbage faster

He used energy to carry the garbage.

He did not have to work because garbage is light.

He caused the garbage to have potential energy when it moved.

He used energy to carry the garbage.

Explanation:

Energy is the ability to do work. When work is done, energy is expended during the process. Work is done if the force applied on an object moves that object through a distance.

In the case where Robin carries the trash from the house to the garbage can outside, work is done because, the force applied by Robin on the trash effectively helps to move the trash from inside the house to the garbage can outside the house. During the process of moving the trash, Robin expends or uses energy to do the work.

From the given options:

He would use less energy if he were to move the garbage faster is wrong because an increase in speed results in an increase in energy

He used energy to carry the garbage is correct because energy is the ability to do work

He did not have to work because garbage is light is wrong because as long as an object is moved a distance, work is done irrespective of the mass of the object.

He caused the garbage to have potential energy when it moved can only be true if he had raised the garbage from the floor to a height above the ground. However, he only moved it fro inside to outside the house.
