The energy associated with motion is called kinetic energy. All energy comes in two basic forms: potential energy, meaning stored energy, and kinetic energy, meaning the energy of movements.Know More
The kinetic energy of an object is the energy that an object possesses due to its motion. In other words, the work needed to move or accelerate an object from a state of rest to its stated velocity is kinetic energy. All moving objects have kinetic energy. The word kinetic has its roots in the Greek word "kinesis," which means motion.
Kinetic energy can further be subdivided into four different categories: mechanical energy, thermal energy, electrical energy and electromagnetic radiation. The motions of people, objects and planets, the vibrations of atoms by sound waves, and the movement of electrons in electricity are a few examples of kinetic energy.Learn more about Physics
A crank and slider mechanism changes straight-line motion into rotation motion. Typically found in piston engines or piston pumps, this design consists of a rod that connects to a rotating driving beam and a sliding body.Full Answer >
An object with more weight resists any change in its speed and has a greater tendency to maintain its motion. This is because an object with more weight is more massive, and an object that is massive has more inertia that causes it to resist any change in speed.Full Answer >
Energy cannot be created, according to the law of the conservation of energy, which was first published in an 1842 scientific article by the German Physicist Julius Mayer. Based on the same principle, energy cannot be destroyed either. In an isolated system, energy can be transformed from one form to another, but the total amount of energy within the system remains constant.Full Answer >
Heat energy is determined by how active the atoms or molecules are in a substance. The atoms and molecules in a hot substance move rapidly and seem excited while the molecules and atoms in a cool substance show less movement.Full Answer >
