How high must you lift a 25-newton book for it to have the same increase in potential energy as a 20-newton book that was lifted 0.5m?
PE=mgh(20 N)(.5 m) = (25 N)xx=0.4 m
How do you calculate potential energy of a 25 newton object lifted 3 meters?
Potential energy = mg * h Given mg = 25 N and h = 3 m So required potential energy = 75 J
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,
Is an example of potential energy?
Newton's Gravity is an example of potential energy, E= -mGM/r and Planck's Energy is an example of potential energy E = hf = hc/r.
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

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.
Who discovered Gravitational potential energy?
Isaac Newton

Who discovered the law of potential energy?
sir Issac newton
What is the si unit for potential energy difference?
Potential energy is measure in Joules (J). A Joule is a Newton*meter (N*m)
When an object's weight and height are multiplied what value do you get?
That is potential energy in inch pounds or Newton-meters

Which gains more gravitational potential energy a 4 N object lifted 3.0 m or a 5 N object lifted 2.0 m?
Let's see. First.....,F = mam = F/am = 4 N/9.8 m/s2= 0.408 kilograms----------------------m = 5 N/9.8 m/s2= 0.510 kilograms-----------------------------secondly......,PE = mghPE = (0.408 kg)(9.8 m/s2)(3.0 meters)= 11.99 Joules==============A 4 Newton object lifted 3 meters gains more potential energy.
What you know about kinetic energy?
Kinetic energy is the energy produced when an object is in motion, When applying a potential energy to an object (REMEMBER THAT POTENTIAL ENERGY IS THE STORED ENERGY FOLLOWED BY AN ACTION) and when the object is released to gain motion it has now a kinetic energy. For example: If a Newton ball from a newton's cradle is taken back and released that potential (BY MOVING IT BACKWARDS) Is transformed into kinetic energy when in motion. Kinetic energy is measured in Ns and the formula is Ek= 1/2mV2.
