In non-uniform circular motion, an object moves in a circular path with varying speed. Since the speed is changing, there is tangential acceleration in addition to normal acceleration. The net acceleration is directed towards the interior of the circle (but does not pass through its center).
A directed trail is a directed walk in which all edges are distinct. [2] A directed path is a directed trail in which all vertices are distinct. [2] If w = (e 1, e 2, …, e n − 1) is a finite directed walk with vertex sequence (v 1, v 2, …, v n) then w is said to be a walk from v 1 to v n. Similarly for a directed trail or a path.
The motion of an object moving in a curved path is called curvilinear motion. [1] Example: A stone thrown into the air at an angle.. Curvilinear motion describes the motion of a moving particles that conforms to a known or fixed curve.
The centripetal force is directed at right angles to the motion and also along the radius towards the centre of the circular path. [ 3 ] [ 4 ] The mathematical description was derived in 1659 by the Dutch physicist Christiaan Huygens .
Projectile motion is a form of motion experienced by an object or particle (a projectile) that is projected in a gravitational field, such as from Earth's surface, and moves along a curved path (a trajectory) under the action of gravity only.
Notice that velocity always points in the direction of motion, in other words for a curved path it is the tangent vector. Loosely speaking, first order derivatives are related to tangents of curves. Still for curved paths, the acceleration is directed towards the center of curvature of the path. Again, loosely speaking, second order derivatives ...
Force-directed graph drawing algorithms assign forces among the set of edges and the set of nodes of a graph drawing.Typically, spring-like attractive forces based on Hooke's law are used to attract pairs of endpoints of the graph's edges towards each other, while simultaneously repulsive forces like those of electrically charged particles based on Coulomb's law are used to separate all pairs ...
A directed graph is weakly connected (or just connected [9]) if the undirected underlying graph obtained by replacing all directed edges of the graph with undirected edges is a connected graph. A directed graph is strongly connected or strong if it contains a directed path from x to y (and from y to x) for every pair of vertices (x, y).
