Web14 apr. 2024 · Kinetic energy is the energy possessed by an object due to its motion. Any object that is in motion has kinetic energy. The kinetic energy of an object depends on its mass and velocity. The formula for kinetic energy is KE = 1/2 mv^2, where m is the mass of the object and v is its velocity. In physics, the kinetic energy of an object is the form of energy that it possesses due to its motion. 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. … Meer weergeven The adjective kinetic has its roots in the Greek word κίνησις kinesis, meaning "motion". The dichotomy between kinetic energy and potential energy can be traced back to Aristotle's concepts of actuality and potentiality Meer weergeven Energy occurs in many forms, including chemical energy, thermal energy, electromagnetic radiation, gravitational energy, electric energy, elastic energy, nuclear energy, … Meer weergeven If a body's speed is a significant fraction of the speed of light, it is necessary to use relativistic mechanics to calculate its kinetic energy.
