Statement I: An object can possess acceleration even at a time when it has uniform speed
statement II: It is possible when the direction of momtion keeps changing.

A

Statement I is true, Statement II is true, Statement II is a correct explanation for Statement I.

B

Statemnt I is true, Statement II is true, Statement II is true, Statement II is false.

C

Statement I is true, Statement II is false.

D

Statement I is false, Statement II is true.

Text Solution

Verified by Experts

The correct Answer is:
A
If the direction of velocity changes (magnitde may or may not change ), we say that velocity changes. If velocity changes, then definitely ther will be acceleration.
