Question

true or false
1. The graph between velocity and time for uniform accelerated motion is a curved line.
2. Motion of an object moving in a circle with constant speed is an example of accelerated niotion.
3. The SI unit of retardation is -ms
4.
The units of speed and velocity are different.
5. Negative velocity is called retardation.
6. Speed is a fundamental physical quantity.
7. If acceleration is zero, the velocity is also zero.
8.
The distance travelled by a body starting from rest and moving with uniform acceleration is
directly proportional to the square of the time taken.
Total distance
9. Average speed =
Total time
10. A satellite going around the earth in a circular orbit at a constant speed is an example of
accelerated motion.
11. A body moving with a constant speed does not necessarily have a constant velocity.
12. A body in a uniform circular motion has a non-zero acceleration
