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
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 car is lifted a certain distance in a service station and therefore has a potential energy relative to the floor If it were lifted twice as high how much potential energy would it have?
The same amount of potential energy again.
How do objects acquire potential energy?
For an object to require potential energy a force must be acting on it in a certain direction. Even though the object doesnt move doesnt mean it has potential energy. The most common force of otential energy is Gravity. When an object is lifted off the ground gravity becomes stronger. For a formula of proof then use E=FxD (Energy=Force applied x Distance travelled). If a ball has been lifted by 10 Meters with a force of 500 Newtons then it has a Potential Energy of 5000 Newton Meters,
How much work is done when 700 n refrigerator is lifted straight up a distance of 4 meters?
Work = Force x distance = 700N x 4m = 2800N•m = 2800 Joules
What is the potential energy of a crate lifted with a force of 100 newtons a vertical distance of 2 meters?
Force x distance = 100 x 2 = 200 newton-meters = 200 joules.
A set of pulleys is used to lift a piano weighing 1000 newtons the piano is lifted?
You need to know the capacity of the pulleys. The pulleys need a total power of over 1000 newtons, if they do then you should be fine.
If it takes Scott 30 newtons of force to move a chair when it is lifted 0.5 meters how much work has Scott done?
force x distance = work 30 N x 0.5 metres = 15joules
How much work is done when a mass weighing 350 N is lifted 4 meters?
1400j
When using a lever do you do less work than if you lifted the object without the lever?
No, the amount of work done will be the same. The lever provides mechanical advantage by multipling force times distance applied. A 1 kg object will need about 10 Joules of work to lift it up a vertical distance of 1 meter, no matter whether it is lifted straight up, or over a greater distance such as up a ramp, or with a lever.

What is the power expended when a barbell is lifted 2.2m in 2 seconds?
The power during the lift is (weight of the barbell in Newtons)/4.4 watts.Note:Power is not "expended". Energy is. Power is the rate at which energy is expended.
