Can the average speed of a body be zero and can the average velocity of a moving body be zero?
Since speed is a scalar quantity, the only way the average speed can be zero is if the instantaneous speed is at all times zero, making it not a moving body, so no on the average speed. The average velocity, on the other hand, can easily be zero. The simplest example is you running in a circle.
Can a body have nonzero average speed but have zero average velocity give example?
Yes, a body can have a nonzero average speed but zero average velocity if it moves around a closed path and returns to its starting point. For example, if a car travels around a circular track at a constant speed, its average speed will be nonzero (as distance is covered), but its average velocity over the entire trip will be zero as the displacement is zero.
Can a body have zero velocity and still acceleration?
No. A velocity indicates a speed and direction. An acceleration is a change in speed or direction.
Can the average speed of a moving body be zero.explain?
no it cannot be zero as the formula for average speed is total distance/total time . if we will come back to the starting point also then also there is distance covered . so it cannot be zero.
Can a body have negative speedwhy?
No. The speed is the length of the velocity vector, and that is always zero or positive.
Can average speed of a body can be zero explain?
Yes, when it comes back to the starting point.
What does it mean for a body to have zero acceleration?
If a body has zero acceleration, it means the body is either at rest or moving at a constant velocity in a straight line. This implies that there is no change in its speed or direction over time.
If net force is zero then the body will move or not?
If the net force on a body is zero, then the body will not accelerate ... its speed and direction of motion won't change. If it was moving a second ago, then it will continue moving at the same speed and in the same direction. If it was not moving a second ago, it won't start moving.
Can particle have zero speed and non zero velocity?
No, a particle cannot have zero speed and non-zero velocity simultaneously. Speed is the magnitude of velocity and if speed is zero, then velocity must also be zero.
Can a body have zero velocity and still be accelerating?
Yes, a body can have zero velocity and still be accelerating if its speed is changing, either increasing or decreasing, over time. This is because acceleration is a measure of how the velocity of an object is changing, regardless of its current velocity.
Can the average speed of a moving body be zero Explain?
Yes, when it comes back to the starting point.
Is it possible for your speed to be zero when your acceleration is not zero?
Yes. Zero acceleration means you are not changing your speed (speed up or slow down) or changing direction. Zero acceleration is a constant speed in a linear direction. A speed implies you are moving.
