Solar energy , Hydro energy , wave energy , Wind energy , Geothermal energy , Biogas plant , Tidal nergy II. Plan to go to a place by a vehicle. Take readings of odometer and speedometer after every 5minu tes till you reach your destination. Record these observations in tabular form; plot graphs between distance-time and speed time. State whether this motion is uniform or nonuniform. III. Answer the following questions: 1. What is the acceleration of a body moving with uniform velocity? 2. What does the slope of a distance-time graph gives? 3. Can displacement be zero even when distance is not zero? Give Example. 4. How can you get speed of an object from its distance – time graph? 5.
