Question

Define Speed

zubi akka naa ungalukku solla vendiyathu ellame enakku Soldringle!! lol​

Answer 1

Answer:

In everyday use and in kinematics, the speed of an object is the magnitude of the rate of change of its position with time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity

Answer 2

Speed is defined as the ratio of distance travelled to the time it took to travel that distance.  

Explanation:

• Speedometers are used to measure the speed of vehicles. Odometers are used to track the distance travelled.
• A graph can be used to calculate speed as well.
• The distance-time graph aids in determining an object's speed. Because speed has only one direction and no magnitude, it is a scalar number.
