## Can the average speed an object travels at ever be equal to the average velocity of the object for the same time interval?

Answer: The magnitude of the average velocity of an object is equal to its average speed, only in one condition when an object is moving in a straight line.

**When can an object’s average speed and average velocity be the same?**

Yes. These are the possible scenario. Scenario 0: When a body travels in a straight line directed to only one point forward at equal distance at equal intervals of time the average speed is uniform and its average velocity velocity equals its average speed. There is no difference between the two quantities.

### Is it possible for an object’s average velocity to be greater than average speed?

Answer: Average velocity is always less than or equal to that of average speed; this is because displacement can never be higher than the distance travelled but the distance travelled can be higher than that of displacement.

**How is it possible that an object has a different speed and velocity on the same trip?**

Objects have the same velocity only if they are moving at the same speed and in the same direction. Objects moving at different speeds, in different directions, or both have different velocities. They represent objects that have different velocities only because they are moving in different directions.

#### Can the average and the instantaneous speed be equal only in the case of constant speed motion?

In practice it is quite difficult to keep the body in uniform motion or constant speed as there are many obstacles in its way. So the instantaneous speed can be equal average speed in only one case, when the body travels with constant speed.

**Can the average speed of a moving body be zero?**

The average velocity of a moving object can be zero in the case of a circular path as displacement will be zero but average speed cannot be zero for a moving object.

## How is average speed different from average velocity?

The average speed is the distance (a scalar quantity) per time ratio. Speed is ignorant of direction. On the other hand, velocity is a vector quantity; it is direction-aware. Velocity is the rate at which the position changes.

**What is the distinction between speed and velocity describe a situation in which an object’s speed is constant but its velocity is not?**

To summarize, an object moving in uniform circular motion is moving around the perimeter of the circle with a constant speed. While the speed of the object is constant, its velocity is changing. Velocity, being a vector, has a constant magnitude but a changing direction.

### Can the average speed be less than the average velocity?

The magnitude of average velocity is always less than or equal to the average speed because displacement is always smaller than or equal to distance. The average velocity of the particle can be positive as well as negative and its positive and negative value depends on the sign of displacement.

**Which of the following situations are possible and give an example for each of these an object with a constant acceleration but with zero velocity?**

When an object is thrown upwards, the maximum height velocity of the body is zero, but the constant acceleration due to gravity is still working. (b) The given statement is possible. The object can move in a certain path with a perpendicular acceleration, in the case of circular motion.

#### Would it be possible for an object to move with constant velocity and changing speed?

No an object can not have a varying speed if its velocity is constant bcoz velocity is a vector quantity,which have magnitude as well as direction . speed is magnitude of velocity . so if speed is varying then velocity is also varying . so therefore it is not possible .

**How would it be possible for an object to be traveling with constant speed and still be accelerating?**

The velocity vector is constant in magnitude but changing in direction. For this reason, it can be safely concluded that an object moving in a circle at constant speed is indeed accelerating. It is accelerating because the direction of the velocity vector is changing.

## How do you find the average speed of a moving object?

To compute the average speed you divide the length of the whole trajectory without considering diretion by the time it took to cover it. If you did not change direction at any time then the magnitude of average velocity and average speed will be the same.

**What is the difference between average velocity and average speed?**

As with speed, it is useful to describe either the average velocity over a time period or the velocity at a specific moment. Average velocity is displacement divided by the time over which the displacement occurs. Velocity, like speed, has SI units of meters per second (m/s), but because it is a vector, you must also include a direction.

### How does direction affect the speed of an object?

Like we saw with displacement and distance in the last section, changes in direction over a time interval have a bigger effect on speed and velocity. Suppose a passenger moved toward the back of a plane with an average velocity of –4 m/s.

**What is the difference between a fast and slow moving object?**

A fast-moving object has a high speed and covers a relatively large distance in a short amount of time. Contrast this to a slow-moving object that has a low speed; it covers a relatively small amount of distance in the same amount of time. An object with no movement at all has a zero speed.
