Question

What is the key difference between motion in one dimension and motion in two dimensions?

विकल्प

• 2D motion takes more time

• Velocity and acceleration are always aligned in 2D

• In 2D, force isn’t always in the same direction as velocity

• 2D motion is only in circles

Answer 1

In 2D, force isn’t always in the same direction as velocity

Explanation:

In 2D motion, force and velocity can point in different directions, so the object moves on a plane, not a straight line.
