Question

if a particle moves with an acceleration then which of following can remain constant 1.both speed and velocity 2.neither speed nor velocity 3. only velocity 4.only speed​

Answer 1

Answer:

4 )only speed

Explanation:

since acceleration=change in velocity divided by time hence if v=constant then there can be no acceleration . whereas if a body is moving in circular path with constant speed then velocity will be vairiable so acceleration is possible hence it is the only possible answer

Answer 2

Answer:

only the speed will remain constant
