Webf = w = m g. The work we do on the rock equals the force we exert multiplied by the distance, d, that we lift the rock. The work we do on the rock also equals the rock’s gain in gravitational potential energy, PEe. W = P E e = m g d. Kinetic energy depends on the mass of an object and its velocity, v. K E = 1 2 m v 2. Webweak interaction, also called weak force or weak nuclear force, a fundamental force of nature that underlies some forms of radioactivity, governs the decay of unstable subatomic particles such as mesons, and initiates the nuclear fusion reaction that fuels the Sun. The weak interaction acts upon left-handed fermions—i.e., elementary particles with half …
WebAlthough the Standard Model describes the three fundamental forces important at the subatomic scale, it doesn’t include gravity. In the subatomic world, gravity is absurdly weak. The gravitational attraction your average pair of protons feel is weaker than their electromagnetic repulsion by a factor of 1036.
