Linear Motion

Simple Velocity

Velocity is displacement upon time.

Velocity and Speed.

  • Speed is Distance upon Time.
  • Velocity is Displacement upon Time.
  • The main difference in speed and velocity is that velocity contains direction along with the mangnitude and speed only contains magnitude.

  • Q:- One car travels 80 kilometers in 20 hours . Find its speed.



    Practice


  • Q:- One car travels with speed of 16 kilometers/hour . In 20 hours , how much distance the car can travel.



    Practice


  • Q:- One car travels with speed of 14 meters/second . How much time will it take to travel 476 meters.



    Practice


  • Q:- The speed of a car is continuosly increasing. it speed increases from 13 kilometers/hour to 574 kilometers/hour in 33 hours. find its acceleration.



    Practice


  • Q:- The speed of a car is continuously increasing. Its acceleration is 9 meters/second2 it means its speed increases by 9 meters/second in every 1 second. Its intial speed is 4 meters/second. Will how long the car take to reach the speed of 346 meters/second.



    Practice


  • Q:- The speed of a car is continuously increasing. Its acceleration is 6 meters/second2 it means its speed increases by 6 meters/second in every 1 second its intial speed is 9 meters/second. After this the car travels for 32 seconds. what will be its final speed.



    Practice


  • Q:- A car travels with the following speeds with the following durations:
