What is the unit of kinetic energy?

joule
The unit of energy in the metre-kilogram-second system is the joule. A two-kilogram mass (something weighing 4.4 pounds on Earth) moving at a speed of one metre per second (slightly more than two miles per hour) has a kinetic energy of one joule.

What are 5 kinetic energy examples?

What is efficiency with example?

Efficiency is defined as the ability to produce something with a minimum amount of effort. An example of efficiency is a reduction in the number of workers needed to make a car. with a minimum of effort, expense, or waste; quality or fact of being efficient.

How to rearrange the formula for kinetic energy?

The formula for kinetic energy is [math]E_{k}=\\dfrac{1}{2}mv^{2}[/math]. If you want to rearrange this equation to express it in terms of mass, start by multiplying both sides by [math]2[/math]:

Which is a factor in the kinetic energy equation?

Kinetic energy is the energy associated with an object’s motion. Mass is a factor in an object’s kinetic energy, but the velocity of the object is the dominating variable. The kinetic energy equation is K = 1 2mv2 K = 1 2 m v 2 where K, m K, m and v v represents kinetic energy, mass, and velocity, respectively.

Which is the best synonym for kinetic energy?

Synonyms for kinetic energy. driving force. electromotive force. locomotion. means of propulsion. motivity.

How is kinetic energy related to velocity and mass?

Kinetic energy is the energy possessed by a body due to its motion. the velocity with which the body is traveling is v . The Kinetic energy is articulated in Kgm 2/s 2. Kinetic energy formula is used to compute the mass, velocity or Kinetic energy of the body if any of the two numerics are given.
