Velocity is speed with direction.

Give examples where a. the velocity of a particle is zero but its acceleration is not zero. b.the velocity is opposite in direction to the acceleration, c. the velocity is perpendicular to the acceleration.

Give examples for the particle where (a) the velocity is in opposite direction to the acceleration (b)the velocity of the particle is zero but is acceleration is not zero.

Name the following. Speed with direction

Which quantity, speed or velocity gives the direction of motion of a body?

A car is moving in east direction. It takes a right turn and moves along south direction without change in its speed. What is the direction of average acceleration of the car?

y component of velocity is 20 and x component of velocity is 10 . The direction of motion of the body with the horizonatal at this instant is

Rate can also be called velocity if the direction is specified.

A,B &C are three objects each moving with constant velocity. A's speed is 10m//sec in a opposite direction of vec(PQ) . The velocity of B relative to A is 6m//sec at an angle of, cos^(-1) (15//24) to PQ . The velocity of C relative to B is 12m//sec in a direction vec(PQ) , then find the magnitude of the velocity of C .

Statement-1: Magnitude of average velocity is equal to average speed, if velocity is constant. Statement-2: It is possible when the direction of motion keeps changing.

A point object 'O' is at the center of curvature of a concave mirror. The mirror starts to move at a speed u, in a direction perpendicular to the principal axis. Then, the initial velocity of the image is
