Speed and velocity

Find the speed and velocities for the case given below.

Instantaneous Speed|Speed Vs Velocity|Acceleration

At what speed the velocity head of a stream of water be equal to 40 cm of Hg

Assertion : Magnitude of average velocity is equal to average speed, if velocity is constant. Reson : If velocity is constant, then there is no change in the direction of motion.

A body at rest can have : A) Speed B) Velocity C) Momentum D) Energy

From the top of a tower, a stone A is thrown upwards and a stone B is thrown downwards with the same speed. The velocity of stone A, on colliding with the ground is :

At what speed, the velocity head of water is equal to pressure head of 40 cm of mercury?

When a car runs on a circular track with a uniform speed, its velocity is said to be changing. This is because :

STATEMENT-1: When a particle moves in a circle with a uniform speed, it velocity and acceleration both changes. STATEMENT-2: The centripetal acceleration in circular motion is depdendent on angular velocity of the body.
