A force of 20 N is required to lift a box the box is lifted from the floor to a shelf that is 2 m high the amount of work done is?

Work Done= Force applied x distance moved in direction of the force. so the work done should in this case be 40J

When you standing on the floor does the floor exert an upward force against your feet How much force does it exert?
Because your feet are not accelerating, the force exerted by the floor upon your feet must be exactly the same as the force exerted by your feet on the floor. If you are standing, the amount of force exerted by your feet, and thus the amount of force exerted by the floor, is equivalent to your weight.
A 50 newton force is required to push a 10 kg box 30 meters across the floor. The box is then lifted up 6 meters and placed on a shelf. How much total work was done?
2,088 J
The measure of force required to move an object?
Force is measured in Newtons (N) The amount of force required = the mass of the object x the acceleration
What are the uses of double pulley in physics?
The amount of force required to lift a weight is inversely proportional to the number of suspension lines. A multiple pulley system allows the load to be distributed across several lines and greatly reduces the amount of force required to lift the weight.. The load that takes mechanical power to lift with a single pulley can be lifted by a single person with a multiple pulley set-up
How many joules of work are done when a 20 newton is lifted 5 meters off of the floor?
The idea here is to multiply the force by the distance.

What is the frictional force required to stop a car?
The same amount of force required to push the car.

The amount of needed to make an object change its depends on the of the object and the required?
. The amount of Force needed to make an object change its motion depends on the Mass of the object and the Force required
What is the amount of force required to keep an object moving?
the same force and dahni is awesome
In comparison to the amount of force required when you are not rotating does pulling in your arms require more amount of force while your sitting on a spinning platform?
yes because of centrifugal force
Force required to accelerate a mass?
Force = mass x acceleration. Any amount of force will accelerate a mass. The amount of force you want to use depends on how quickly you want to accelerate something.
Can the number of pulleys affect the amount of force to lift a heavy objects to a high place?
Increasing the number of pulleys divides the force required to lift up a heavy object; increasing the number of pulleys decreases the force needed by the person (or motor) pulling the first end of the pulley system. However, it is important to know that it does not affect the total work needed to lift up the object. As the force is decreased, the distance of rope needed increases to compensate for a conserved amount of work required for the load to be lifted.
A ..is required to change the speed and direction of a moving body?
Force. Change in speed and direction is change in velocity. Change is velocity is called acceleration a=F/m.. The amount of change is the amount of acceleration and that depends inversely on the mass and directly on the force.
