Question

Is it possible to accelerate a body, if its speed is constant?
​

Answer 1

Answer:

yes,it is possible by applying some external unbalanced force.

Answer 2

Yes.

Explanation :

It is possible in the case of Uniform Circular Motion.

• When a body is set into Circular motion with constant speed, it still has an acceleration towards center which is called Centripetal Acceleration .
• This acceleration is due to the Force which is responsible for the object to do Circular motion.

In the above scenario we can see that the body has an acceleration and net acceleration is not zero but the speed is still constant.

Points to consider :

• The "velocity" of the object keeps on changing as the direction of motion keeps on changing.
• Velocity is constant magnitude-wise (speed).

Hope this helps.
