Define velocity. How it is different from speed .
Answers
Answer:
Velocity of a body is the distance travelled by it per unit time in a given direction.
Velocity = Displacement/Time.
The difference between speed and velocity is that speed has only magnitude or size, it has no specific direction, but velocity has magnitude as well as direction. So, we call speed as a scalar quantity but velocity is a vector quantity.
Answer:
Velocity - the rate of displacement of a moving object over time.Velocity is a vector quantity, which depends on direction as well as magnitude.

Basically, an object’s speed tells you how fast it’s going. Its velocity tells you how fast it’s going in a certain direction. You use speed measurements in yo ur da ily life, but ph.ysicists depend on velocity measurements more frequently in their work.

• How Velocity Works
Velocity depends on the direction an object travels. It incorporates the speed of that object as well as the difference between its st.arting place and its en ding place. You use the sa me units for speed (m/s, kph, and mph) when measuring velocity, but factoring in its direction.

You need to calculate the velocity of objects when determining where they might go. Like speed measurements, velocity can be measured by an object’s average velocity and its ins tantaneous velocity.
