Question

Which of the following statements best describes the relationship between force and work?

a. Work equals force divided by distance.
b. Force and work are two terms for the same thing.
c. Work is equal to certain forces, like gravity and friction.
d. Work is done when a force moves an object over a distance.

Answer 1

The correct relationship between force and work is that work is done when a force moves an object over a distance, represented by the equation W = Fd, where W is work, F is the force, and d is the distance. So the correct option is d.

Step-by-step explanation:

The statement that best describes the relationship between force and work is option d: Work is done when a force moves an object over a distance. In physics, work is a concept that refers to the process when a constant force causes an object to be displaced. The equation for work done on an object by a force is W = Fd, where W stands for work, F represents the magnitude of the force applied, and d is the distance over which the force acts in the direction of the force.

Therefore, the idea that work could be equal to a force divided by distance, or that work and force are the same, or that work is equal only to certain forces, like gravity and friction, is incorrect. Work indeed requires both a force and a movement in the direction of that force.

Answer 2

a)., b)., and c). are completely false.
There isn't a grain of truth among them.

In Physics, the technical definition of 'Work' is (force) times (distance).
