What is the formula of the potential energy?
The formula for potential energy is PE = mgh, where PE is the potential energy, m is the mass of the object, g is the acceleration due to gravity, and h is the height of the object above the reference point.
Does gravitational potential energy depend on mass and speed?
On mass yes, on speed no.The formula for gravitational P.E. is: PE = mgh, that is, mass x gravity x height.On mass yes, on speed no.The formula for gravitational P.E. is: PE = mgh, that is, mass x gravity x height.On mass yes, on speed no.The formula for gravitational P.E. is: PE = mgh, that is, mass x gravity x height.On mass yes, on speed no.The formula for gravitational P.E. is: PE = mgh, that is, mass x gravity x height.
When a child rides a skateboard down an inclined ramp when the skateboard gets to exactly onehalf the starting height the child's kinetic energy?
First off an assumption: dissipative forces are negligible - this means no energy goes into overcoming friction and air resistance. It also means that the total energy of the system "U" is a constant. The total energy is the sum of the kinetic and potential energies: U=Ke+Pe Potential energy is a function of height and mass, kinetic is a function of mass and velocity. So at the top when the skateboard isn't moving: Ke=1/2mv2 =0 as velocity =0 Pe=mgh U=Pe+0=mgh Where h is the full height of the ramp. Halfway down the ramp the height =h/2 so Pe=mgh/2 Remembering U must be the same as it was at the top of the ramp: U=mgh=Pe+Ke=mgh/2 +Ke So solving gives Ke=mgh/2.
What is the potential energy of a 100kg object when it is raised to a height of 5.00m?
The potential energy of the object can be calculated using the formula PE = mgh, where m is the mass (100kg), g is the acceleration due to gravity (9.81 m/s^2), and h is the height (5.00m). Substituting the values, we get PE = 100 * 9.81 * 5 = 4905 Joules.
Formula to calculate potential energy?
The potential energy can be exactly defined as the work required to place an object into a certain position - which is the integral of the dot product of force and displacement. In the case of gravitational potential energy, and for small differences in altitude (so that gravity doesn't change too much), that simplifies to mgh (mass x gravity x height).
What does the letters stand for in this formula PE equals mgh?
PE=MGH means the potential energy equals to the mass times the gravity times the height
What does pe equals mgh stand for when you are talking about energy?
Potential Energy
What energy does a cyclist at the top of a hill have?
PE = mgh
What is the formula of the potential energy?
The formula for potential energy is PE = mgh, where PE is the potential energy, m is the mass of the object, g is the acceleration due to gravity, and h is the height of the object above the reference point.
How do you solve the equation you equals mgh for h?
In the equation "you = mgh", divide both sides of the equation by mg, or you/mg = mgh/mg. The answer then is h = you/mg.

What is the gravitational potential energy of a 95 kg rock at the top of a 45m cliff?
PE = mgh PE = 95 x 45 x 9.81 kg.m.ms-2 = 41.94 KJ
If a 2 kg mass has 40 j of potential energy with respect to the ground approx how far is it located above the ground?
Use the formula PE = mgh (potential energy = mass x gravity x height). Use 9.8 (which you might round to 10), for gravity.Use the formula PE = mgh (potential energy = mass x gravity x height).

How do you find potential energy of an object?
Potential Energy = mass * 9.80 m/s^2 * height PE = mgh
What is the potential energy of a mass of 500 g raised to a height of 2 m?
The formula for working out Potential enery is: PE = mgh - where g equals to the acceleration due to gravity (which is 10 newtons) - mass should be in Kg's - and height in meters - final answer should be in Joules (J) Therefore substitute it in :-) Pe = (500g = 0.5kg) x (10N or more exact 9.8N) x (2 meters) Pe = 10 Joules of potential energy with a object weighing 500g (or 0.5 kg) and from a height of 2 meters
