Is it possible to have an accelerated motion with a constant speed? Explain.

Short/Brief Note

Solution

Yes, it is possible to have accelerated motion with constant speed, when a body is moving in a circular path. The body changes its path so there is a change in direction (velocity) but its speed remains the same.
