Differentiate between a) velocity and acceleration b) speed and velocity
Answers
velocity is the speed of an object in particular direction.
acceleration is the rate of change pf velocity
speed is the movement wrt an observer of an object in no particular direction
velocity is also the movement of an object wrt an observer and in a particular direction.
Answer:
a ) Velocity is the rate of change of displacement. Acceleration is the rate of change of velocity. Velocity is a vector quantity because it consists of both magnitude and direction. Acceleration is also a vector quantity as it is just the rate of change of velocity.
b ) Speed is defined as the distance travelled by a body in a given interval of time. Velocity is defined as the displacement of a body in a given interval of time. It is a scalar quantity.
Explanation:
The difference between velocity and acceleration can be drawn clearly on the following grounds: The velocity of an object refers to the speed in a specific direction. ... Velocity is nothing but the rate of change of displacement. On the other hand, acceleration is the rate of change of velocity with respect to time.
