Bill is often seen pulling large objects—hammers, saws, bicycles, weightlifting equipment, camping equipment, sports gear, and the like—out of his trousers. In the British sci-fi series Doctor Who many objects are shown to be "bigger on the inside", most notably the TARDIS , although the Doctor has also stated that pockets on their clothes ...
Forklifts are powered vehicles (gas, diesel, electric) that are often used in facilities to move heavy items. The truck can pick up significantly heavier objects compared to the human and move it to a new location. Since the forks can be adjusted, the height of the lift can also be adjusted so that employees can lift in a more neutral position.
A contact force is any force that occurs as a result of two objects making contact with each other. [1] Contact forces are very common and are responsible for most visible interactions between macroscopic collections of matter. Pushing a car or kicking a ball are some of the everyday examples where contact forces are at work.
In mechanics, compression is the application of balanced inward ("pushing") forces to different points on a material or structure, that is, forces with no net sum or torque directed so as to reduce its size in one or more directions. [1]
Tension is the pulling or stretching force transmitted axially along an object such as a string, rope, chain, rod, truss member, or other object, so as to stretch or pull apart the object. In terms of force, it is the opposite of compression. Tension might also be described as the action-reaction pair of forces acting at each end of an object.
The concept of force makes the everyday notion of pushing or pulling mathematically precise. Because the magnitude and direction of a force are both important, force is a vector quantity. The SI unit of force is the newton (N), and force is often represented by the symbol F. Force plays an important role in classical mechanics.

Propulsion is the generation of force by any combination of pushing or pulling to modify the translational motion of an object, which is typically a rigid body (or an articulated rigid body) but may also concern a fluid. [1] The term is derived from two Latin words: pro, meaning before or forward; and pellere, meaning to drive. [2]
