Find work of an object at constant velocity

In summary, when lowering an object at constant velocity, the total work done on the block is equal to zero. This is due to the fact that the work done by gravity on the block is negative, while the work done by the hand on the block is positive. Additionally, the work done by the block on the hand is also negative, resulting in a net work of zero. This is all determined by the formula for work, which is force multiplied by distance.

I lower an object at constant velocity.
What is the sign of the total work done on the block?
What is the sign of the work done by gravity on the block?
What is the sign of the work done by my hand on the block?
What is the sign of the work done by the block on my hand?


I know that work = Force * distance.

Any help is much appreciated!

Welcome to PF! :smile:

Next time use the template provided and show your attempt of solution, please.

What determines the sign of work?

Related to Find work of an object at constant velocity

1. What does it mean for an object to have constant velocity?

Constant velocity means that the object is moving at a steady rate in a straight line, with no changes in speed or direction.

2. How do you find the work of an object at constant velocity?

The work of an object at constant velocity can be found by multiplying the force applied to the object by the distance it travels in the direction of the force.

3. Does the work done on an object at constant velocity change over time?

No, the work done on an object at constant velocity remains constant over time because the object is not accelerating and therefore, the force and distance remain the same.

4. Can an object have constant velocity and still have work done on it?

Yes, an object can have constant velocity and still have work done on it if there is a force acting on it in the direction of its motion. This work is equal to the force multiplied by the distance traveled.

5. How does the work of an object at constant velocity relate to its kinetic energy?

The work done on an object at constant velocity is equal to the change in the object's kinetic energy. This means that the more work is done, the greater the change in kinetic energy of the object.
