Question

9. State which of the following situations are possible and give
an example for each of these:
(a) an object with a constant acceleration but with zero velocity
(b) an object moving with an acceleration but with uniform
speed.
(c) an object moving in a certain direction with an
acceleration in the perpendicular direction.​

Answer 1

Answer:

Explanation:

a) Possible. When an object is thrown upwards and returns to its original position, acceleration is not zero (g) but velocity is zero

b) Possible, in uniform circular motion , direction keeps changing so acceleration is present but speed is uniform. (Note : Velocity is not uniform)

c)Possible, The object moving in a circular direction with the acceleration towards the centre and perpendicular to movement. Circular motion is a good example for this.
