Question

In a straight line motion for a given finite time interval, the average velocity of particle is

Answer 1

Answer:

average velocity =total displacement /total time taken

Answer 2

The average velocity of a particle in a straight line motion for a given finite time interval is ratio of displacement to time taken.

• Average velocity is defined as the ratio of an object's displacement from point a to point b to the time required to complete that displacement.
• Average velocity is defined algebraically as v = d/t, where d represents the distance travelled and t represents the time it took.
• Average velocity is not only about the distance covered or displacement but the direction of it also matters.
• A particle travelling in a straight line can have an average velocity of zero over a period of time.
• For that the particle must turn 180 degrees at some point, at which time its instantaneous velocity will be zero.
• This is only conceivable if the particle has the same initial and terminal positions.
