Rotational kinetic energy describes the energy of motion resulting from an object’s rotation or circular motion. Recall that linear kinetic energy of a mass m moving with speed v is given by 1/2mv 2.This is a straightforward calculation for any object moving in a straight-line path. It applies to the object’s center of mass, allowing the object to be approximated as a point mass.

Torsion spring - Wikipedia

en.wikipedia.org/wiki/Torsion_spring

A torsion spring is a spring that works by twisting its end along its axis; that is, a flexible elastic object that stores mechanical energy when it is twisted. When it is twisted, it exerts a force (actually torque) in the opposite direction, proportional to the amount (angle) it is twisted.

This topic will explain the rotational kinetic energy formula with examples. Let us learn it! Concept of Rotational Kinetic Energy. Rotational kinetic energy is the energy absorbed by the object by the virtue of its rotation. The equations for linear and rotational kinetic energy can be expressed in the same way as to the work-energy principle.

Up until now, we have discussed the magnitude of the angular velocity ω = d θ / d t, ω = d θ / d t, which is a scalar quantity—the change in angular position with respect to time. The vector ω → ω → is the vector associated with the angular velocity and points along the axis of rotation. This is useful because when a rigid body is rotating, we want to know both the axis of rotation ...

This means that linear molecule have the same equation for their rotational energy levels. The only difference is there are now more masses along the rotor. This means that the inertia is now the sum of the distance between each mass and the center of mass of the rotor multiplied by the square of the distance between them 2 .

The total energy of the universe is always conserved. The same statement can be stated in other words: the energy can never be created nor be destroyed, but it can only be transferred from one form to another. There are different types of energies: for example, kinetic energy, heat energy, light energy, sound energy, etc. The sum of all these energies of the universe is always constant.

Rotational kinetic energy = ½ moment of inertia * (angular speed) 2. When the angular velocity of a spinning wheel doubles, its kinetic energy increases by a factor of four. When an object has translational as well as rotational motion, we can look at the motion of the center of mass and the motion about the center of mass separately.

The potential energy of the pendulum can be modeled off of the basic equation PE = mghwhere g is the acceleration due to gravity and h is the height. We often use this equation to model objects in free fall.However, the pendulum is constrained by the rod or string and is not in free fall. Thus we must express the height in terms of θ, the angle and L, the length of the pendulum. Thus h = L(1 – COS θ)When θ = 90° the pendulum is at its …

Similarly, during rotational motion when a torque is applied to angularly accelerate a body, the work done by the torque leads to an increase in kinetic energy. Hence the total energy of the body also increases. This video says that the total energy of the body remains constant, hence there is a need for rotational potential energy in order to balance out the increase in the kinetic energy.
