Which has more kinetic energy




















Jan 21, Explanation: The problem doesn't specify this, but if are to assume that both the massive object and the lighter object are moving with the same velocity , then the answer would be yes.

Related questions How do matter and energy interact? Question 50ca2. Question cf. Question d. Question What is potential energy? Question d Kinetic and Potential Energy :. Kinetic Energy :. Is energy of motion. Anytime matter is in motion it has kinetic energy.

Unit: Joule. The faster an object moves, the more kinetic energy it has. The more mass an object has, the more kinetic energy it has. According to this equation, what effects K. Velocity Potential Energy :.

Potential energy is called the energy of position. The sun actually doesn't cool objects, but the sun never shines on an object on Earth all the time! Hydropower harnesses the kinetic energy of moving water as it falls in a waterfall or hydroelectric dam. Tidal power harnesses the energy of moving water as it moves back and forth due to tides. Explore this simulation to see how gravitational potential energy and kinetic energy go back and forth but keep mechanical energy the same.

Notice how mechanical energy can be lost and turned into thermal energy, but the total amount of energy still stays the same:. Thermal energy temperature is a special type of kinetic energy.

It is not the energy of a whole object itself moving - it is the total energy of motion, rotation, and vibration of the atoms and molecules inside an object. In a gas or gas mixture, like air , the motion and rotation of individual gas particles makes up this energy.

In a solid , like a table, the thermal energy exists as vibration of atoms or molecules. Total thermal energy also includes some atomic forms of potential energy , but the kinetic energy of particles is the easiest to focus on. The temperature of an object is determined by its total microscopic kinetic energy.
