It could be both, most likely putting books into your backpack
If the backpack is being carried at a constant speed, there is no change in velocity, which means there is no net force acting on it. Since work is the result of a force acting over a distance, and no force is causing the backpack to accelerate or decelerate, no work is being done on the backpack.
D=1.250m.
The work done on a 25 kg backpack when you walk 100 m horizontally depends on the force needed to move the backpack and the distance you carry it. Without knowing the force applied to move the backpack, we cannot calculate the work done. Work is defined as force multiplied by distance in the direction of the force, so we need this additional information to provide an accurate answer.

As the backpack gets higher, the distance over which you are lifting it increases, requiring more work to overcome gravity. The force needed to lift the backpack is directly proportional to the distance it is lifted and the weight of the backpack. This is due to the gravitational force acting on the backpack.
The work done in raising the backpack can be calculated as the change in potential energy. Using the formula, work = force x distance, we find that the work done is approximately 740 Joules.
Not many gym bags work as backpacks, but many backpacks work as gym bags.
When choosing a backpack for biking to work, look for features like padded shoulder straps, a chest or waist strap for stability, reflective elements for visibility, waterproof material, and compartments for organization.
