5 Questions
What is work in the context of physics?
The energy transferred to or from an object via the application of force along a displacement
When does a force do positive work?
When it has a component in the direction of the displacement of the point of application
What mathematical operation gives the work done when both force and displacement are constant?
The dot product of force and displacement vectors
In what scenario does a force do negative work?
If it has a component opposite to the direction of the displacement at the point of application
How is the work done by a gravitational force when a ball is held above the ground and then dropped?
Positive, equal to the weight of the ball multiplied by the distance to the ground
