Question

what may be negative speed or velocity​

Answer 1

Answer:

Velocity is positive if an object is moving to the right and it is negative if an object is moving to the left. Speed tells how fast an object is moving without saying anything about its direction. Speed is always positive. Speed is the "absolute value" of the velocity.

Answer 2

Answer:

• Velocity can be negative or positive.

Explanation:

Speed:

1. The distance travelled per second by a moving object is called its speed.
2. It is a scalar quantity. The speed does not tell us the direction of motion.
3. The speed is always positive since direction is not taken into consideration.
4. After one round in a circular path, the average speed is not zero.

Velocity:

1. The distance travelled per second by a moving object in a particular direction is called its velocity.
2. It is a vector quantity. The velocity tells us the speed as well as the direction of motion.
3. The velocity can be positive or negative depending upon the direction of motion.
4. After completing each round in a circular path, the average velocity is zero.
