How much work is done if a force of 20 N is applied on an object that remains stationary?
20 joules
Calculate the work done in lifting a 500-N barbell 2.2m above the floor what is the potential energy of the barbell when it is lifted to this height?
Work = Force x distance So since the barbell is 500N and the barbell travels 2.2 meters it becomes 500N x 2.2m = 1100 joules (N x m)
Why is it easy to push a brick gently but gets hurt when kick it?
Inertia. It takes force to overcome the brick's weight and friction. If applied slowly, the work can be done with deforming your foot. Done quickly, and the fleshy part of your foot will be squashed, before the brick starts to move.
If a force of 100 newtons was exerted on an object and no work was done the object must have?
The object must be stationary. Work done happens when the object is moving in the direction of the force- if it is staying still, there is no work done!
Is work done if you lift a brick?
Yes, work is done if you lift a brick.
How much work is done if a woman is pushing a cart with 500N force along the 7m aisle?
Just multiply the force times the distance. This assumes the force is applied in the direction of the movement.

How much work is done by a weight lifter when he holds a weight of 80kgs on his shoulder for two minutes?
none. work is done when a force is applied thru a distance. holding something stationary does no work.

How much work is done when a 23 n brick is lifted to a height of 2.3 m?
Work = force * distance Work = 23N * 2.3 meters = 53 Joules of work is done ==================
What is he definition of work?
Work is the product of a force and the distance through which it acts in the direction of the force. In order for work to be done, the object must move in the direction of the force. If you push on a brick wall until you exhaust yourself and the wall doesn't move, you have not done any work. If you push on a box and it moves in the direction that you are pushing it, you have done work.
How long did it take to build the original great wall of china?
1 year-not done yet brick brick brick
How much work against gravity is done by a 500N person to climb 4 M in 3s?
Work = (force) times (distance) = (500) x (4) = 2,000 joulesThe time he spends doing it makes no difference. If he climbs in 3 secondsor 3 months, the amount of work is the same.
