... 1. A car travelling at 50 km/hr hits a stone wall and is brought to rest. A passenger wearing
a seatbelt comes to rest in 1 m. What is the acceleration experienced by this passenger?
2. A passenger in the same car and not wearing a seatbelt strikes the windshield and comes to
rest in 0.01 m. ...
... Wave propagation underlies a huge number of physical and biological phenomena. However in everyday life waves are most commonly encountered in the form of light and sound,
and the behaviours of both these phenomena are governed by linear wave equations. The
study of such equations has been one of th ...

In physics, the n-body problem is the problem of predicting the individual motions of a group of celestial objects interacting with each other gravitationally. Solving this problem has been motivated by the desire to understand the motions of the Sun, Moon, planets and the visible stars. In the 20th century, understanding the dynamics of globular cluster star systems became an important n-body problem. The n-body problem in general relativity is considerably more difficult to solve.The classical physical problem can be informally stated as: given the quasi-steady orbital properties (instantaneous position, velocity and time) of a group of celestial bodies, predict their interactive forces; and consequently, predict their true orbital motions for all future times.To this purpose the two-body problem has been completely solved and is discussed below; as is the famous restricted 3-Body Problem.
