Motion in Striaght Line (Physics)
Motion in a Straight Line. If an object changes its position with respect to its surroundings with time, then it is called in motion. If an object does not change its position with respect to its surroundings with time, then it is called at rest.
Motion in Plane (Physics)
Motion in a Plane. Motion in a plane is also referred to as a motion in two dimensions. For example, circular motion, projectile motion, etc. For the analysis of such type of motion, the reference point will be made of an origin and the two coordinate axes X and Y.
Law of Motion (NCERT Notes)
Newton's Three Laws of Motion. Newton's three laws of motion may be stated as follows: Every object in a state of uniform motion will remain in that state of motion unless an external force acts on it. Force equals mass times acceleration [ ]. For every action there is an equal and opposite reaction.
