When does the average velocity becomes zero

Why does the average velocity becomes zero? This means that when a body changes position in a particular direction at first, and changes the position in the opposite direction by the same amount, the displacement is zero. Also, for a uniformly accelerating body, the average velocity is zero if the final velocity is equal to the negative of the initial velocity. What does it mean when average velocity is negative? When average velocity is positive, it usually means that the object is moving forward from its starting point. When average velocity is negative, it usually means that the object is moving backward. To find where the average velocity is greatest, simply find between which two points the slope is the greatest. Can velocity be negative? Velocity: The velocity of an object is the change in position (displacement) over a time interval. Velocity includes both speed and direction, thus velocity can be either positive or negative while speed can only be positive. Another way to say this is that speed is the absolute value of velocity. Can the average acceleration be negative? Note that the average acceleration can be positive, negative, or zero. A negative acceleration is simply an acceleration in the negative direction. Keep in mind that although acceleration points in the same direction as the change in velocity, it is not always in the direction of the velocity itself. Can velocity be positive and acceleration negative? We can also define these two acceleration when a...

Because.... for avg velocity ......when displacement becomes zero it will also become zero... avg velocity = displacement/total time but for avg speed it cannot be zero....total distance travelled cannot be zero. therefore it will not be zero avg speed= total distance / total time...

(b) The magnitude of average velocity in an interval is equal to its average speed in that interval. (c) It is possible to have a situation in which the speed of a particle is always zero but the average speed is not zero. (d) It is possible to have a situation in which the speed of the particle is never zero but the average speed in an interval is zero.

Select the incorrect statements from the following. S1: average velocity is path length divided by time interval S2: in general, speed is greater than the magnitude of the velocity. S3: A particle moving in a given direction with a non-zero velocity can have zero speed. S4:the magniude of average velocity is the average speed.

The air molecules surrounding us are not all traveling at the same speed, even if the air is all at a single temperature. Some of the air molecules will be moving extremely fast, some will be moving with moderate speeds, and some of the air molecules will hardly be moving at all. Because of this, we can't ask questions like "What is the speed of an air molecule in a gas?" since a molecule in a gas could have any one of a huge number of possible speeds. So instead of asking about any one particular gas molecule, we ask questions like, "What is the distribution of speeds in a gas at a certain temperature?" In the mid to late 1800s, James Clerk Maxwell and Ludwig Boltzmann figured out the answer to this question. Their result is referred to as the Maxwell-Boltzmann distribution , because it shows how the speeds of molecules are distributed for an ideal gas. The Maxwell-Boltzmann distribution is often represented with the following graph. You might think that the speed located directly under the peak of the Maxwell-Boltzmann graph is the average speed of a molecule in the gas, but that's not true.

• Average Velocity is the total displacement of a body in total time while average speed is the total distance traveled by the body in total time. • Speed is a scalar quantity while velocity is a vector quantity. • The average speed of a body in motion can never be zero whereas the average velocity of a body can have zero value. For example: • If we consider a body in motion having the same initial and final point, its displacement is zero while the distance covered is not zero. • Therefore it has zero velocity and a non-zero speed. Hence, the average velocity of a body is zero when the average speed is non-zero.

Explanation: • As we all know, speed depends on the distance traveled in a time interval. • It does not depend on the direction, it is a scalar quantity. • So, when a body is moving then it will definitely travel a particular distance, in a certain time. • Then speed or average speed will have some magnitude or non-zero value. Hence, the average speed cannot be zero.
