Assertion: For motion in two or three diemensions, velocity and acceleration vecotrs must have any angle between `0^(@) and 90^(@)` between them.
Reason: For such motion velocity and acceleration of an object is always in the opposite direction.

What is the angle between velocity and acceleration vector in a circular motion?

Assertion In projectile motion, the angle between instanteneous velocity vector and acceleration vector can be anything between o to pi (excluding the limiting case) Reason In projectile motion, acceleration vector is always pointing vertically downwards. (Neglect air friction.)

Which of the quantity, velocity or acceleration determines the direction of motion ?

Assertion : In projectile motion, the angle between the instantaneous velocity and acceleration at the highest point is 180^(@) . Reason : At the highest point, velocity of projectile will be in horizontal direction only.
