your muscles are still contracting. Hence, your arms lift as a restult of not being able to let go
No
By NEWTONS.
answer is because lifting a box is gravitational P.E and thinking is not MIGHT BE RIGHT MIGHT NOT
Lifting loads heavier than about 50 pounds will increase the risk of injury, or mechanical lifting devices such as duct lifts to hold large.

A 100 cm door makes sense. A doorway with hinges on the side needs to be large enough to allow people and things to pass but not so big that it gets difficult to open and close. To manipulate a much wider door may require separating the door into sections with hanging supports or wheels positioned underneath or being opened by lifting as in typical garage doors. A 100 meter doorway might be appropriate for an aircraft hanger

Lifting an object against gravity requires more force than pulling it along a horizontal surface because you are working against the force of gravity. When lifting, you are fighting against the weight of the object in addition to any other resistance present, such as friction. Pulling, on the other hand, only requires overcoming the frictional force.
Using gloves for weight lifting provides benefits such as improved grip, reduced friction and calluses on the hands, and added protection against blisters and injuries.
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.
Lifting a dumbbell is considered isotonic exercise because the muscle length changes as the weight is lifted against gravity. Isometric exercise, on the other hand, involves static muscle contractions without changing muscle length.
"Are lifting" is a verb. It's the present progressive tense of lifting. "You" is a pronoun.
convergent lifting :low pressure area convectional lifting : local surface heating orgraphic lifting : physical barrier frontal lifting(cold and warm fronts) : contrasting air masses
Full finger weight lifting gloves provide benefits such as improved grip, protection against calluses and blisters, increased comfort, and better wrist support during workouts.
Three lifting mechanisms for air are thermal lifting, dynamic lifting, and convergence lifting. Thermal lifting occurs when air near the ground is heated and rises. Dynamic lifting occurs when air is forced upward due to the movement of weather systems. Convergence lifting occurs when air flows together at the surface and is forced to rise.
