Explain the relationship between work, force, and displacement in physics.

In physics, work is the energy transferred to or from an object via the application of force along a displacement. For a constant force aligned with the direction of motion, the work equals the product of the force strength and the distance traveled. Signup and view all the answers

What is the definition of positive work in physics?

A force is said to do positive work if when applied it has a component in the direction of the displacement of the point of application. Signup and view all the answers

What is the definition of negative work in physics?

A force does negative work if it has a component opposite to the direction of the displacement at the point of application of the force. Signup and view all the answers

Provide an example of positive work in a physics context.

When a ball is held above the ground and then dropped, the work done by the gravitational force on the ball as it falls is positive, and is equal to the weight of the ball (a force) multiplied by the distance to the ground (a displacement). Signup and view all the answers

Give an example of negative work in a physics context.

If a ball is thrown upwards, the work done by the gravitational force is negative, and is equal to the weight multiplied by the displacement in the upwards direction. Signup and view all the answers
