(b) What changes continuously in uniform circular motion?
2. State whether the following statement is true or false :
Earth moves round the sun with uniform velocity.
3. A body goes round the sun with constant speed in a circular orbit. Is the motion uniform or accelerated ?
4. What conclusion can you draw about the velocity of a body from the displacement-time graph shown below :
5. Name the quantity which is measured by the area occupied under the velocity-time graph.
6. What does the slope of a speed-time graph indicate ?
7. What does the slope of a distance-time graph indicate?
8. Give one example of a motion where an object does not change its speed but its direction of motion changes continuously.
9. Name the type of motion in which a body has a constant speed but not constant velocity.
10. What can you say about the motion of a body if its speed-time graph is a straight line parallel to the time axis ?
