Likewise, as long as acceleration is negative, velocity decreases even if acceleration is increasing. Share Cite Follow answered Aug 4, 2015 at 10:45 fkraiem 3,109 1 12 11
Web18 aug. 2024 · Answer: (b) When a body is moving in a circle, its speed remains same but velocity changes due to change in the direction of motion of body. According to first law of motion, force is required to change the state of a body. As in circular motion the direction of velocity of body is changing so the acceleration cannot be zero.
