Question

State whether True or False :
Motion in 3-Dimension can't be represented with the help of vectors.

• A. True
• B. False

Answer 1

The correct option is B False

Motion in 3-Dimension can be represented with help of vectors. For example

Displacement can be written as $s=s_x\hat{i}+s_y\hat{j}+s_z\hat{k}$

Velocity can be written as $v=v_x\hat{i}+v_y\hat{j}+v_z\hat{k}$

Acceleration can be written as $a=a_x\hat{i}+a_y\hat{j}+a_z\hat{k}$
