Question

write the difference between speed and velocity​

Answer 1

Answer:

Step-by-step explanation:

• Speed is a scalar quantity,which is the ratio of distance and time and it is always positive for a moving object/body.

• Velocity is a vector quantity,which is the ratio of displacement and time and it may be positive,negative or zero for a moving object/body.

Answer 2

Speed:-

• The distance travelled per second by a moving object is called it's speed.
• It is a scalar quantity. The speed doesn't tell us the direction bof motion.
• The speed nis always positive since direction is not taken into consideration.
• After one round in a circular path, the average speed bis not zero.

Velocity :-

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

Hope it helps uh :)
