# If the total displacement is zero can the average velocity be nonzero?

345

No, you cannot have a zero displacement and a nonzero average velocity. If the object has not moved any where how can you attain a nonzero velocity? You cannot.

## Related Questions Average velocity is def.ined as the ratio of total displacement to total time taken. Average Velocity is displacement over total time.  Since average velocity is total displacement over total time, the answer is 0m/s, because there is no displacement. (Remember, velocity has a direction unlike speed). v = &Delta;dt / &Delta;t Average velocity = Total displacement / time If you want to be more specific: v = ds/dt Instantaneous velocity = derivative of displacement with regard to time Average velocity in a direction is calculated as the displacement in that direction divided by the total time taken. As the time interval is reduced, the displacement over that period also reduces and the limiting value of that ratio is the instantaneous velocity. The average velocity is pretty close to zero. Velocity is a vector, so its average value is the total displacement divided by the total time. Since the racquet probably starts and finishes in the player's bag in the player's home, the average velocity is zero. The average amount of motion can be determined by the average speed or velocity of an object. The average speed can be calculated by the total distance divided by the total time. Speed is a scalar quantity. The average velocity can be calculated by the total displacement divided by the total time. Velocity is a vector. it can be calculated at a particular instant as it is total displacement in given time It's as simple as total displacement divided by total time. Be careful though. If this is a velocity problem, displacement does not always equal distance. The total displacement divided by the time. The slope of the displacement vs. time graph. Every time the unicycle returns to its starting point, the average velocity equals zero. The total displacement divided by the time. Every time the unicycle returns to its starting point, the average velocity equals zero. C. The total displacement divided by the time.  The person travels a total of 4000 m in 400 seconds, so their average speed is 10m/s. However velocity is a vector quantity, and is defined as displacement/time. The total displacement is only 400 m, so the average velocity is just 1m/s. displacement =velocity multiplied by time plus half of acceleration multiplied by time squared Yes, if, for example, a car races around a circuit, its total displacement is zero and so its velocity, at the end of every lap, is zero. total velocity * * * * * It is the average speed, not velocity which is a vector. Yes it is possible. If a body goes round a circular path then distance covered by one full rotation will be 2 pi r But the total displacement is 0. Hence the average speed exists but average velocity does not exist. 0.0002315 m/s OR 0.0008333 km/hour The velocity of an object is the rate of its change in position in a certain direction. Velocity is a vector quantity; this means that it has both a magnitude and direction. To find the average velocity of an object in motion, the following equation is used: average velocity= (total displacement)/ (total time elapsed) The SI units of velocity are "m/s" , but any distance unit over any time unit is also acceptable. Solving for the velocity asked for: First let's change hours to seconds: (12 hours ) x (6o minutes/hour )x (60 seconds/minute)= 43200 seconds Finding the velocity: average velocity= (displacement)/ (time)= 10m/ 43200 seconds= 0.000231481 m/s Never.Average velocity is total displacement (final position minus initial position) divided by the total time: vave = (xf-xi)/tAcceleration is the rate at which your velocity is changing or change in velocity over time: a= (vf-vi)/tThese two quantities may have the same numerical value but will never have the same units.Average velocity for a trip can equal instantaneous velocity at a certain point during the trip, however, at any time during a trip in which the velocity is constant or at half way through the total time of a trip where the acceleration is constant.  the instantaneous velocity or speed is the speed a body travels at a particular and average velocity is the total distance an object Displacement in any interval of time may be zero,positive or negative.Imagine that a car begins traveling along a road after starting from a specific signpost. To know the exact position of the car after it has traveled a given distance, you need to know not only the miles it traveled but also its heading.The displacement, defined as the change in position of the object, is a vector with the magnitude as a distance, such as 10 miles, and a direction, such as east. Velocity is a vector expression with a magnitude equal to the speed traveled and with an indicated direction of motion. For motion defined on a number line, a positive or negative sign specifies the direction.Average velocity is mathematically defined asaverage velocity = total displacement/time elapsedNote that displacement (distance from starting position) is not the same as distance traveled. If a car travels one mile east and then returns one mile west, to the same position, the total displacement is zero and so is the average velocity over this time period. Displacement is measured in units of length, such as meters or kilometers, and velocity is measured in units of length per time, such as meters/second (meters per second). Velocity is an instantaneous measure. Mathematically, it is the limiting value of the change in the position vector divided by the change in time as the latter tends to zero. Over larger time periods, the average velocity is the total change in the position vector divided by the total change in time. If velocity is constant, the average velocity will be the same as the instantaneous velocity.
