Zero speed and non-zero velocity.

Text Solution

AI Generated Solution

To determine whether a body can have zero speed and non-zero velocity, we need to analyze the definitions of speed and velocity. ### Step-by-Step Solution: 1. **Understanding Speed and Velocity**: - Speed is defined as the distance traveled per unit time. It is a scalar quantity, meaning it has magnitude only. - Velocity, on the other hand, is defined as the displacement per unit time. It is a vector quantity, meaning it has both magnitude and direction. ...

An object experiences a net zero external unbalanced force. Is it possible for the object to be travelling with a non-zero velocity? If yes, state the conditions that must be placed on the magnitude and direction of the velocity. If no, provide a reason.

The average velocity of a particle moving on a straight line is zero in a time interval. Assertion :- It is possible that the instantaneous acceleration is never zero in the interval. Reason :- It is possible that the instantaneous velocity is never zero in the interval.

Assertion: The average velocity of a particle is zero in a time interval. It is possible that the instantaneous acceleration is never zero in the interval. Reason: The magnitude of average velocity in an interval is equal to its average speed in that interval.

Assertion: When a particle moves with constant velocity its average velocity, its insttantaneous velocity and its speed are all equal in magnitude. Reason: If the average velocity of a particle moving on a straight line is zero in a time interval, then it is possible that the instantaneous velocity is never zero in the internal.

Can a body have a. Zero instantaneous velocity and yet be accelerating? b. Zero average speed but non-zero average velocity? c. Negative acceleration and yet be speeding up? d. Magnitude of average velocity be equal to average speed ?

Is it possible that two non - zero vectors multiply and give a zero result ?

The correct statement from the following is A body having zero velocity will not necessarily have zero acceleration A body having zero velocity will necessarily have zero acceleration A body having uniform speed can have only uniform acceleration A body having non-uniform velocity will have zero acceleration

Assertion : Average velocity can’t be zero in case of uniform acceleration. Reason : For average velocity to be zero, a non zero velocity should not remain constant.

Can a body have zero velocity and finite acceleration?
