Question

5. Define average speed', 'acceleration, distance and displacement

​

Answer 1

Answer:

Average speed is defined as the total distance travelled by the body in total time i.e. Average Speed=Total timeTotal distance. It is a scalar quantity. Its unit is m/s.

Answer 2

Explanation:

$\mathbb{\huge{\pink{\underline{\underline{\underline{\underline{AnsWer}}}}}}}$

1. The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time.
2. acceleration is the rate of change of the velocity of an object with respect to time.
3. Distance is a numerical measurement of how far apart objects or points are.
4. displacement is a vector whose length is the shortest distance from the initial to the final position of a point P undergoing motion.
