Equations of motion force the object exerts. Replacing momentum by mass times velocity, the law is also written more famously as since is a constant in Newtonian mechanics. Newton's second law applies to point-like particles, and to all points in a rigid body. They also apply to each point in a mass continua, like deformable solids or fluids, but the motion of the system must be accounted for, see material derivative. In the case the mass is not constant, it is not sufficient to use the product rule for the time derivative on the mass and velocity, and Newton's second law requires some
Landscape of the Body Landscape of the Body Landscape of the Body is a two-act play by John Guare, first performed in 1977. The play is episodic and non-linear, as it travels back and forth in time. The plot centers on a woman named Betty, whose son, Bert, was recently murdered and decapitated in lower Manhattan. The location of the first and last scenes are the same. They take place on a boat, with Betty, who throws bottles filled with notes overboard, and an absurdly disguised Detective Holahan. Initially, Holahan accuses Betty of killing her son, but Betty insists this is not true. The
