What is Motion in Two Dimensions ?

Motion in Two Dimensions An object moving in a plane is said to have two-dimensional motion. The two-dimensional motion is equal to the vector sum of two one-dimensional motions along the mutually perpendicular direction. Let the position of point $P$ at a time $t$ be given by position vector $\overrightarrow{\mathrm{OP}}=\overrightarrow{\mathrm{r}}$ $\vec{r}=\hat{i} r \cos \theta+\hat{j} r \sin \theta=\hat{i} x+\hat{j} y$ Also Read JEE Physics Notes To watch Free Learning Videos on JEE by Kota’...
