Down: 1) SI unit of energy.2) unit of energy used globally in the power, steam generation and heating and air conditioning industries.3) amount of energy transferred by a force.4) energy of an object consisting of loose material, held together by gravity alone, is the amount of energy required to pull all of the material apart, to infinity.5) effectiveness of a machine and is defined as the ratio of mechanical advantage to velocity ratio.8) energy of a body or a system due to the position of the body or the arrangement of the particles of the system9) rigid object that is used with an appropriate fulcrum or pivot point to multiply the mechanical force that can be applied to another object.12) energy which causes or is released by the physical distortion of a solid or a fluid.15) unit of energy and mechanical work in the centimetre-gram-second (CGS) system of units.16) 1 newton meter=1 kg times meters squared divided by seconds squared17) force times cos theta times distance19) a unit of measurement for energy equal to the amount of heat required to raise a gram of water one degree celsius. In most fields, it has been replaced by the joule. Across: 6) orce that does zero net work on a particle that travels along any closed path in an isolated system.7) any device that only requires the application of a single force to work.10) factor by which a mechanism multiplies the force put into it. 11) the total amount of energy in an isolated system remains constant, although it may change forms.13) extra energy an object possesses due to its motion, defined as the work needed to accelerate the body from rest to its current speed.14) flat surface whose endpoints are at different heights.17) SI derived unit of power, equal to one joule per second.18) work one system does (or can do) on another system20) rate at which work is performed or energy is transmitted. It is the amount of energy required or expended for a given unit of time.21) unit of energy often used also in theoretical physics as a unit of mass. It is the amount of kinetic energy gained by a single unbound electron when it passes through an electrostatic potential difference of one volt, in vacuo.22) wheel with a groove along its edge for holding a rope or cable or belt.
