Question

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 a constant acceleration but with uniform speed (c) an object moving in a certain direction with an acceleration in the perpendicular direction​

Answer 1

a) an object with a constant acceleration but with zero velocity.

Answer:- This is not possible because acceleration is the change of velocity and if there is no velocity there will be no acceleration also.

(b) an object moving with a constant acceleration but with uniform speed.

Answer:- This is not possible because acceleration is the change of velocity and it is not possible with uniform velocity.

c) an object moving in a certain direction with an acceleration in the perpendicular direction​.

Answer:- This is possible when a circular motion is occurring.
