Work = (force) x (distance) = (10) x (4) = 40 joules

How much work is done when 1000 kg is lifted 75 meters?
work done is = to force multiply by displacement here force is = 1000x10 N and dispacement is 75m = 75x104
How much work is done when an object with a mass of 78 kilograms is lifted through a height of 6 meters?
78*6*9.8 N = 4586.4 N
How does an inclined plane change how work is done?
vertical lift versus slope the work done is the same (force * distance), but with a say 30 degree slope you need only half the force but need to travel twice as far to raise the load the same height vertically
What is gravitational potential energy deduce an expression for it?
GPE is energy a body has by virtue of its position in a gravitational field. if the field is uniform (as near the surface of the Earth) then the work done to raise a body to a particular height above the earth is the same as the GPE gained by the body. Work done = force x distanced moved along the line of the force, W=Fd In this case, the force is the weight mg of the body and distance = height h above the Earth, so GPE = mgh
How much work is done when a mass weighing 350 N is lifted 4 meters?
1400j
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 ==================
How much work is done when 1000 newton cart is lifted to a height of to 2 meter?
In this case, work is the product of force and distance. (This assumes that both are in the same direction, and that the force doesn't change.)
How much work is done by gravity as the riders are lifted to a height of 60 meters?
Gravity does not lift. The force is doing the work by lifting the riders. When the riders come down from the 60 meter height, then gravity will be at work.
An object of mass 4.5 is lifted through a distance of 10m H ow much work is done?
I believe that when you say 'lifted through', you mean lifted to a height of 10m. If so, the amount of work is such: Work= Force x Distance which have the units (Joules = Newtons x meters) When the object is lifted, it increases in its potential energy. The equation for this is: Potential energy = mass x gravitational force x height = 4.5 x 9.81 x 10 =441.45 Joules As 1 joule = 1 newton x meters and we have 441.45 Joules, 441.45 joules of works is done! :D
How much work is done when 1000 kg is lifted 75 meters?
work done is = to force multiply by displacement here force is = 1000x10 N and dispacement is 75m = 75x104
When is work said to be done against the force of gravity?
All bodies with mass are attracted to the Earth by gravity, so when a body is raised you must do work to raise it. This work is equal to force x height, if force is in Newtons and height in meters, the work is in units of Joules.
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
How much work is done when a 48-kg stack of books are lifted 2m with a net force of 25 N?
Workdone =force * distance 25N * 2m = 50Nm OR 50joules
When a ball rises vertically to a height h and returns to its original point of projection the work done by the gravitational force is?
The work done would be calculated by 2mgh. The force on the ball is calculated by mg, and work done is by Fd, where d is 2h (the force acts on both upwards height and downwards height, thus twice the distance).
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.
How much work is done when a 100 N force moves a block 59 m?
Just multiply the force times the distance.
How much work is done when an object with a mass of 78 kilograms is lifted through a height of 6 meters?
78*6*9.8 N = 4586.4 N
