0.8 When do the distance and displacement of a moving object have the same magnitude?
0.9 Give an example of a body which may appear to be moving for one person and staionary for the othe
Q.10 What do you mean by average speed? What are its units?
0.11 What is the difference between uniform velocity and non-uniform velocity?
hier moving with a mifarm clocity change?
Answers
Answer:
1) Distance and Displacement are equal in magnitude when the object is moving along a striaght line.
2)Here, it can be travelling in bus. In bus for the passenger the bus is stationary and for the person outside the bus...the bus is to be in motion.
3)If an object covers a Distance ( s ) in Time ( t ) then the average speed is...(Total distance covered/Total time taken). Its SI units is same as of speed which is m/s.
4) A Body has a uniform velocity if it travels in specified direction in a straight line and moves equal distances in equal intervals of time.
Just its opposite if a body does not covers equal distances in equal intervals of time then it is said to be variable or non-uniform speed.
