Draw a diagram showing that the acceleration of a body in uniform circular motion is directed perpendicular to its motion.

Velocity vector and acceleration vector in a uniform circulat motion are related as

Derive equation of uniform accelerated motion.

Assertion (A) The speed of a body in uniform circular motion is constant. Reason ( R) In uniform circular motion, the acceleration of the body is constant .

The waves in which the particles of the medium vibrate in a direction perpendicular to the direction perpendicular to the direction of wave motion are known as

In a projectile motion the velocity (a) is always perpendicular to the acceleration (b) is not always perpendicular to the acceleration (c) is perpendicular to the acceleration for one instant only (d) is perpendicular to the acceleration for two instants.
