Q: If a stationary force applied to an object, the object moved in the direction of force, is expressed as a result of force and displacement, it is called –
  • A. Retardment
  • B. Work done
  • C. Impulse
  • D. Acceleration
Correct Answer: Option B - If a force applied to an object, the object moved in the direction of force, is expressed as a result of force and displacement, it is called work done. Work is a dot product of force and displacement. The dot product of vector quantities (force and displacement) is always scalar which means it has only magnitude not direction. Work done (W) = Force (F). Displacement (d)
