Which of the following statements about work in physics is correct?
- Work is the distance traveled by an object divided by the time taken.
- Work is the force applied to an object divided by the distance traveled.
- Work is the energy transferred to or from an object via the application of force along a displacement. (correct)
- Work is the product of the force and the velocity of an object.
When does a force do positive work on an object?
When does a force do positive work on an object?
- When the force is applied at an angle to the displacement of the object.
- When the force is applied in the same direction as the displacement of the object. (correct)
- When the force is applied perpendicular to the displacement of the object.
- When the force is applied in the opposite direction as the displacement of the object.
