Question

Give an example of motion with
i) Acceleration a = 0 but velocity is non zero
ii) Displacement = 0 but distance
travelled is non zero​

Answer 1

Answer:

1.idk

sorry

2.a athlete in a running race

distance is the whole ground

Answer 2

Explanation:

• Easiest example: a projectile. At the peak of the trajectory, a vertically thrown object has gravity acting on it (accelerating it downwards at 9.8 m/s/s) while its velocity is zero. which has zero velocity at and non-zero acceleration at .
• displacement can be zero even if a body has covered some distance. For example , consider two points A and B 1km far from each other, if a body travels from A to B and comes back to A , its distance will be (1+1) km while its displacement will be 0 , because object is back to its initial position.
