WebJun 4, 2024 · Work. In physics, work is related to the amount of energy transferred in or from a system by a force. It is a scalar-valued quantity with SI units of Joule . Work can be represented in a number of ways. For the case where a body is moving in a steady direction, the work done by a constant force acting parallel to the displacement is defined as. WebAcceleration is the derivative of velocity with respect to time: a ( t) = d d t ( v ( t)) = d 2 d t 2 ( x ( t)) . Momentum (usually denoted p) is mass times velocity, and force ( F) is mass times acceleration, so the derivative of momentum is d p d t = d d t ( m v) = m d v d t = m a = F .
