s it possible to have motion in the absence of a force? Is it possible to have force in the absence of motion |
| Answer» <p>Yes, it is possible to have motion in the absence of force. An object moving with a constant velocity has zero net external force on it, but it still remains in motion.</p><p>Also, it is possible to have force in absence of motion. Statics is the study of forces in systems in equilibrium--i.e., that have no motion.</p><p>Here are some sub-fields in increasing order of complexity:</p><p>Statics of particlesStatics of rigid bodiesStatics of fluidsStatics of deformable solids--further divided into 'strength of materials' and theory of elasticity and theory of plasticity </p> | |

What is energy? Why is it generated nor destroyed? |
| Answer» <p>Ans :- In physics, thelaw of conservation of energystates that the total energy of an isolated system cannot change—it is said to beconservedover time. Energy can be neither created nor destroyed, but can change form; for instance, chemical energy can be converted to kineticenergy</p> <p>energy is the capability to do work.</p><p>According to the law of conservation of energy, energy can neither be created nor destroyed.
