Kinetic energy = (1/2)mv2, where m is mass and v is velocity.

In this case, mass is 4 kg and velocity is 5 m/s, so K = (1/2)(4)(5)2 = 50 Joules.

(The units of energy are Joules, as long as everything is measured in kilograms, meters, and seconds.)

KE = 1/2mass*velocity squared

KE = 1/2(24 kg)(2 m/s)2

= 48 Joules

Kinetic Energy (KE) can be represented by the following formula: KE = 0.5mv2.

In this case kinetic energy would equal 480,000 joules.

What types of meters are used in Energy Management Systems?

Energy Management Systems use many different types of meters. Energy Management Systems install and supply gas meters, water meters, and electric meters.


A 5kg object is being lifted to a height of 8 meters and is dropped what is the kinetic energy of the object at 2 m?

After falling 6 meters, potential energy corresponding to those 6 meters will be converted to kinetic energy. The potential energy (for the 6 meters) is mgh = (5 kg)(9.82 m/s2)(6 m) = 294.6 J, so that is also the kinetic energy, since potential energy has been converted to kinetic energy.After falling 6 meters, potential energy corresponding to those 6 meters will be converted to kinetic energy. The potential energy (for the 6 meters) is mgh = (5 kg)(9.82 m/s2)(6 m) = 294.6 J, so that is also the kinetic energy, since potential energy has been converted to kinetic energy.After falling 6 meters, potential energy corresponding to those 6 meters will be converted to kinetic energy.

What is the energy of a system by virtue of its motion?

That's called kinetic energy. The formula is: Kinetic energy = (1/2) x mass x velocity2. If mass is in kilograms, and velocity (or speed, really) in meters per second, the energy will be in Joules.

Is touching a kinetic energy?

Kinetic energy is the energy of motion. Your touching finger has mass and is moving some meters per second, so that motion is kenetic energy.


How much kenetic energy of 1000 kilogram car traveling of 50 kilometer per hour?

Convert the speed to meters/second (dividing km/h by 3.6 gives you m/s), then insert the numbers into the standard formula for kinetic energy (1/2 m v2).


How many joules of kenetic energy does 1 kg book have when it is tossed across the room at a speed of 2 miles per second?

Needs conversion. 2 m/s (1609 meters/1 mile) = 3218 meters per second ( fast!! ) Kinetic Energy = 1/2(mass)(velocity in meters per second)^2 KE = 1/2(1 kg)(3218 m/s)^2 = 5177762 Joules ( 5.2 X 10^6 Joules ) --------------------------------------------------

Why watts is used in consumer power meters?

Consumers do not normally have 'power meters'; they normally have 'energy meters', which are used measure the amount of energy being purchased from the electricity supply company. 'Power meters' are wattmeters, which measure power -i.e. the rate at which you use energy. Energy meters measure energy in units called kilowatt hours, whereas wattmeters measure power in watts. Your electricity supply company isn't really interested in the power of your residence, only the energy consumed.
