Question

Give me two examples for linear motion and reciprocating motion

Answer 1

Answer:

Linear Motion

1. A ball thrown straight up and falling back straight down.
2. An athlete running 100 my along a straight track.

Answer 2

Answer: Linear motion (also called rectilinear motion) is a one-dimensional motion along a straight line, and can therefore be described mathematically using only one spatial dimension.

EX-Parade of the soldiers .

Car moving at constant speed.

Reciprocating motion, also called reciprocation, is a repetitive up-and-down or back-and-forth linear motion. It is found in a wide range of mechanisms, including reciprocating engines and pumps. The two opposite motions that comprise a single reciprocation cycle are called strokes.

EX- A crank on a mechanism is used to turn circular motion into reciprocating motion.

In rack and pinion mechanisms, a table is moved up and down the central pillar of a drill as a crank is turned. This makes it easy to move a table with minimal effort.
