Concept of velocity:

Velocity is the rate of change of distance with respect to time and it is a vector physical quantity. That is, it is measured by magnitude and direction. The average velocity of an object is the rate at which it moves during a given period of time, regardless of how much its velocity changes through it.

What is the fastest velocity in the universe?!

The highest speed in the universe is the speed of light and equals 299,792,458 m / s, which equates to rotating around the Earth seven times in one second. Matter cannot completely reach the speed of light, as this would require an infinite amount of energy.

Who is the first to measure velocity?

The Italian physicist Galileo Galilei was considered the first to measure velocity by measuring the distance traveled and the time it took to travel this distance.

Types of velocity:

• Constant velocity: is the speed at which an object travels equal displacements in equal times.
• Variable velocity: It is the speed at which an object cuts different displacements at different times.
• Instantaneous velocity: It can be defined as the velocity at a certain moment or the constant velocity over a very short period of time. By looking at the speedometer, a person can measure the instantaneous speed of the car at any moment. If the vehicle is traveling at 50 km per hour, after a full hour it will travel 50 km if it is traveling at the same speed during that period.
• Average velocity: It is defined as the total distance traveled during a time.
• Transverse velocity: is the distance traveled per unit of time, while transverse velocity is the linear velocity of an object moving along a circular path.
