Distinguish between rectilinear motion and motion in a plane
Answers
Answer:
A body/ object is said to be in linear motion when it travels along a straight line or along a curve in a plane. Example- Athlete running along a straight path. Rectilinear motion ( is also a type of linear motion) which can be described by by a moving body/object that travels only straight path.
Gravitational forces acting on objects resulting in free fall is an example of rectilinear motion. Kids sliding down from a slide is a rectilinear motion. The motion of planes in the sky is a rectilinear motion.
Motion in a plane is also referred to as a motion in two dimensions. For example, circular motion, projectile motion, etc. ... Motion in a plane refers to the point where we consider motion in two dimensions as only two dimensions makes a plane.
