Question

Q. give an example where motion is two dimensional but acceleration is one dimensional.

Answer 1

Example:- The motion of project light is two dimensional but its acceleration is one dimensional  

Answer 2

$\textsf{TYPES OF DIMENSIONAL MOTION }$

$\bullet \:\mathfrak{ one\;dimensional\:motion }$

$\bullet \:\mathfrak{ two\;dimensional\:motion }$

$\bullet \:\mathfrak{ three\;dimensional\:motion }$

$\mathcal{ONE \;DIMENSIONAL\:MOTION:-}$

⇾$\text{When a body moves along a straight line,it is said to be in one dimensional motion.}$

⇾$\text{In one-dimensional motion,only one - coordinate of the position of the body changes with time.}$

⇁ $\mathbf{Example:-}$

⇏$\text{ Motion of a car moving on a straight road.}$

⇏$\text{ Motion of a freely falling body.}$

⇏ $\text{Motion of a person running on a straight race track.}$

$\mathcal{TWO \;DIMENSIONAL\:MOTION:-}$

$\textsf{When a body moves along two dimensions , it is said to be in two-}$$\textsf{dimensional motion.In simple words,Motion of a body in }$$\textsf {plane is a two dimensional motion.}$

⇾It includes the motion along a curved path like projection,circular motion.

⇁ $\mathbf{Example:-}$

↛ A roller coaster doing a loop.

↛ Motion of a car during a circular turn.

↛ Motion of billiards ball.

$\mathcal{THREE\:DIMENSIONAL \:\:MOTION:-}$

$\textsf{When a body moves along three dimensions 'X','Y'&'Z' ,it is said to be in }$$\textsf{three dimensional motion. (Or) Motion of a body in space }$$\textsf {is called as three dimensional motion.}$

⇁ $\mathbf{Example:-}$

⇨ $\textsf{Motion of a flying bird.}$

⇨$\textsf{ Movement of gyroscope.}$

⇨$\textsf{ Motion of an aeroplane.}$

⇨$\textsf{ Motion of a kite.}$

$\mathbb{EXTRA\:INFORMATION}$

⇾$\textsc{If one dimensional motion is motion in straight line say in- X - direction.}$

⇾$\textsc{Then,two dimensional motion is motion in a plane in X &}$ $\textsc{ and Y direction at the same time.}$
