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's acceleration is constant and downward due to the force of gravity In projectile motion, but the object's velocity reverses direction during the object's motion. This is because of the inertia described in Newton's first law of motion and because acceleration and velocity are two different physical quantities. Velocity is the speed and direction of an object, while acceleration is the rate that the velocity changes.Full Answer >
Sound energy is a form of energy that is associated with the vibrations of matter. This energy is a mechanical wave, so it needs a transmission medium to pass through, such as air and water.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 >
