Motion
Assignment on based topic speed and its type, velocity and its type, acceleration positive and negative acceleration
1. Define speed of a body. What are its units?
2. How does instantaneous speed differ from the average speed?
3. What is meant by uniform speed ? How does variable speed differ from the uniform speed?
4. Define the term velocity. Is velocity a scalar or a vector quantity? What are the SI units of velocity?
S. When is the velocity said to have changed?
6. What is meant by average velocity of a body moving in a particular direction?
7. How does speed differ from velocity?
8. When de the velocity and speed of a moving body become identical?
9. What does the odometer of an automobile measure?
10. What is the nature of the distance-time graphs for uniform and nonuniform motion of an object?
11. An electric train is moving with a velocity of 120 km/h, How much distance will it move in 305.
12. Define acceleration. Express the acceleration of a body in terms of its initial and final velocities. What are the units of
acceleration
13. What is the negative acceleration?
14. A scooter acquires a speed of 36 km/h in 10 seconds after the start. Calculate acceleration of the scooter.
15. A car has a uniform acceleration of 4 m s. What distance will it cover in 10 s after start?
16. Draw a velocity vs time graph of a stone thrown vertically upwards and then falling downwards after attaining the maximum height.
