Question

Assertion : the velocity of an object is the speed of an object in a particular direction Reason : Si unit of velocity is same as speed (a) both A and R are true.but R is not the correct explanation of A
(b) Both A and R are true and R is the correct explanation of A​

Answer 1

Answer:

Both Assertion and Reason are true and R is the correct explanation of A.

Answer 2

The correct option is (a) Both A and R are true. But R is not the correct explanation of A.

• In a single direction, the velocity of an object will be equal to the speed of the object. This is one of the definitions of velocity too.
• If a body travels in one direction only, then its speed will be equal to its velocity.
• SI unit of velocity and speed are the same as both represent distance travelled in a certain frame of time. Its unit is m/s.
• Thus, both assertion and reason statements are true but the reason is not the correct explanation of assertion.
