Work is defined as a force acting through a distance (a length of space), energy is always equivalent to the ability to exert pulls or pushes against the basic forces of nature, along a path of a certain length. In the International System of Units (SI), energy is measured in joules, but in many fields other units, such as kilowatt-hours and kilocalories, are customary. All of these units translate to units of work, which is always defined in terms of forces and the distances that the forces act through.

Saponification is a process that produces soap, usually from fats and lye. In technical terms, saponification involves base (usually caustic soda NaOH) hydrolysis of triglycerides, which are esters of fatty acids, to form the sodium salt of a carboxylate. In addition to soap, such traditional saponification processes produces glycerol. “Saponifiable substances” are those that can be converted into soap. Vegetable oils and animal fats are the main materials that are saponified. These greasy materials, triesters called triglycerides, are mixtures derived from diverse fatty acids. Triglycerides can be converted to soap in either a one- or a two-step process.

Acceleration, in physics, is the rate of change of velocity of an object with respect to time. An object’s acceleration is the net result of any and all forces acting on the object, as described by Newton’s Second Law. Newton’s second law of motion states that acceleration is directly proportional to net force when mass is constant.

A fuse wire is a safety wire connected in series with the live wire that has high resistivity and low melting point. Fuses are always connected in series with the component(s) to be protected from overcurrent. In case of any large current supply or malfunctioning in the electric connections, it melts and breaks the electric circuit.

The hydraulic brake is an arrangement of braking mechanism which uses brake fluid, typically containing glycol ethers or diethylene glycol, to transfer pressure from the controlling mechanism to the braking mechanism. It works on the principle of Pascal’s law which states that “pressure at a point in a fluid is equal in all directions in space”. When pressure is applied on a fluid it travels equally in all directions so that uniform braking action is applied on all wheels.
