Kinetic energy unit math. Kinetic energy is an example of scalar quantity which means that the quantity has only magnitude and no direction. Solve for problems 9 16. The joule j is the si unit of energy and equals kg m 2 s 2. Kinetic energy mv2.
An object s kinetic energy is the energy due to motion. Translational kinetic energy of a body is equal to one half the product of its mass m and the square of its velocity v or 1 2 mv 2. Potential energy is energy stored in matter. Kinetic energy can be defined mathematically as ke 1 2mv2 ke 1 2 mv 2 where ke kinetic energy m mass and v velocity.
The cgs unit of kinetic energy is erg. Energy is the capacity to do work or to produce heat. Then choose the correct formula to use to solve. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity having gained this energy during its acceleration the body maintains this kinetic energy unless its speed changes the same amount of work is done by the body when decelerating from its current.
For a rotating body the moment of inertia i corresponds to mass and the angular velocity omega ω corresponds to linear or translational velocity. Kinetic energy is the energy due to motion. Ke m v 2. I hand out rubber bands and ask each student to shoot at the ceiling and demonstrate kinetic energy.
Unit 2 lesson 2 kinetic and potential energy. The kinetic energy of an object equals one half the object s mass m times the square of its volume v. Ke 1 2 m v2 or gpe mgh. You serve a volleyball with a mass of 2 1 kg.
Energy is defined as the capacity to do work or to produce heat. I ask how can chuck get energy the students reply by pushing him i explain how that is the energy of movement or kinetic energy. M is the object s mass kg v is the object s speed m s. Kinetic potential energy displaying top 8 worksheets found for this concept.
In physics the kinetic energy ke of an object is the energy that it possesses due to its motion. The ball leaves your hand with a. We throw the angry bird toy to one another with different amounts of kinetic energy. How is the kinetic energy of an object calculated.
