Short Answer Based questions for Motion
- What is unit of acceleration?
- What is zero uniform velocity motion?
- A body moving in a circle with constant speed. Is it having acceleration?
- A body goes from point A to B and then return then from B to A. what is the total displacement?
- Acceleration is a vector quantity True or false?
- What is the path of a velocity –time graph of a body moving with uniform acceleration
- What all ways the velocity of the body can be changed?
- What is average speed?
Solutions
- m/s2
- It is the object at rest
- Yes as the direction of the velocity is changing
- Zero
- True
- Straight line
- We can change either in magnitude or direction or we can change both the magnitude and direction
- Average speed is the ratio of total distance travelled to the total time taken
