How Do You Calculate Rotational Kinetic 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 .

How do you calculate stress of a material?

As expected by the units, stress is given by dividing the force by the area of its generation, and since this area (“A”) is either sectional or axial, the basic stress formula is “σ = F/A”.


What are the uses of refrigerant?

A refrigerant is chemical compound that is used as the heat carrier, which changes from gas to liquid and then back to gas in the refrigeration cycle. Refrigerants are used primarily in refrigerators/freezers, air-conditioning, and fire suppression systems.

The alleles an individual has at a locus is called a genotype. The genotype of an organism is often expressed using letters. The visible expression of the genotype is called an organism's phenotype.


What are the two types of substitution reactions?

Substitution Reactions – Types

Substitution Reactions are of two types naming nucleophilic reaction and electrophilic reactions.


How do you explain area and volume?

The area is the amount of space occupied by a two-dimensional flat object in a plane. Volume is defined as the space occupied by a three-dimensional object. The unit of area is in square units. The unit of volume is in cubic units.


What are examples of qualitative research questions?

Examples of qualitative research questions:

  • What is it like growing up in a single-parent family in a rural environment?

What is mocking in the Bible?

According to the gospel narratives, Jesus had predicted that he would be mocked (Matthew 20:19, Mark 10:34, and Luke 18:32). The mocking of Christ took place in three stages: immediately following his trial, immediately following his condemnation by Pontius Pilate, and when he was being crucified.


What is the straight line treatment of optics?

More to Know! If an opaque object on the path of light becomes very small, light has a tendency to bend around it and not walk in a straight line – an effect known as the diffraction of light. Then the straight-line treatment of optics using rays fails.

  6. Tip #5: Come up with the answers yourself.


What are uniform and non-uniform motion give four examples for each type of motion?

Answer: When a body covers equal distances in a straight line, equal intervals of time are called uniform motion. Example: a car moving at 20km/h in a straight line. When a body covers unequal distance in equal intervals of time in a straight line is called non-uniform Example : spinning wheel.


What is uniform circular motion Give 4 examples of it?

Uniform Circular Motion Examples
