How do you find the potential energy of a rod?
How do you find the potential energy of a rod?
- Before starting here are some assumptions as.
- Length of rod=L.
- Radius of rod= R.
- And mass of rod= M.
- Acceleration due to gravity =g.
- Case 1:- In horizontal position –
- Center of mass lies at hight of R so the potentil energy= M×g×R.
- Case 2:- in vertical position –
What is potential energy calculate the potential energy of a body of mass 10 kg kept at height of 2 m above the ground?
Masss= m = 2 kg; height = h= 20 m; g= 10 m/s2 (assumption, acceleration due to gravity); Potential Energy = mgh = 12*20*10 = 2400 Joules.
What is the potential energy of an object at a height?
Since the gravitational potential energy of an object is directly proportional to its height above the zero position, a doubling of the height will result in a doubling of the gravitational potential energy. A tripling of the height will result in a tripling of the gravitational potential energy.
What is rotational potential energy?
From Wikipedia, the free encyclopedia. Rotational energy or angular kinetic energy is kinetic energy due to the rotation of an object and is part of its total kinetic energy.
How do you calculate rotational energy?
Rotational kinetic energy can be expressed as: Erotational=12Iω2 E rotational = 1 2 I ω 2 where ω is the angular velocity and I is the moment of inertia around the axis of rotation. The mechanical work applied during rotation is the torque times the rotation angle: W=τθ W = τ θ .
