Lifting a box involves exerting force to overcome gravity and move the box vertically. Work is defined as force applied over a distance, so lifting a box requires work to be done against the force of gravity as the box is raised. Thus, lifting a box involves transferring energy to the box to move it to a higher position.
It takes more work to lift the box because lifting against gravity requires more force than pushing along a ramp.
An example of doing work is lifting a box from the ground to a shelf. In this scenario, work is being done against gravity to move the box vertically.
An example of doing work is lifting a box from the floor to a shelf. In this scenario, you are exerting a force to move the box against the force of gravity, thereby performing mechanical work on the box.
When lifting a box from the floor, the energy is transferred from your muscles to the box in the form of mechanical energy. The potential energy of the box increases as it is lifted against gravity. Additionally, some energy is also transferred to the surroundings in the form of heat due to friction and air resistance.
A ramp can make lifting a box easier by spreading the work over a longer distance. Instead of lifting the box straight up, you can use the ramp to slide it up gradually, which requires less force at any given moment. This allows you to achieve the same amount of work with less effort.
answer is because lifting a box is gravitational P.E and thinking is not MIGHT BE RIGHT MIGHT NOT

Yes, lifting a pencil requires using muscles, which is considered physical work. However, in the context of physical activity or exercise, lifting a pencil would not be considered a significant form of exercise.
Work is the usage of energy to make something happen. A very simple example is the act of pushing or lifting a box.
In physics, work is performed when a force is applied to an object and causes it to move in the direction of the force. In this scenario, the man lifting the box is applying a force to move the box upwards against the force of gravity. The work done is equal to the force applied multiplied by the distance the box is lifted.
The work done in lifting the box is given by W = force x distance = 100 N x 10 m = 1000 J. Since power is the rate at which work is done, the power used in lifting the box is P = work / time = 1000 J / 5 sec = 200 Watts.
The work done in lifting a 250 N box up a distance of 1.5 m is 375 Joules. This is calculated by multiplying the force (250 N) by the distance (1.5 m) over which the force is applied.
Work is done by a force acting on a mass when that mass is displaced (moved).Basically, more work is required to move a mass through a greater distance, similarly more work is required to move a greater mass though the same distance.Providing all other things are equal, if the same box is moved through a distance of two metres you do more work than moving the box through one metre.
