Question

If an object moves in a circle at a constant speed, its velocity vector will be constant. true or false

Answer 1

False

Step-by-step explanation:

For the vector to remain the same, the magnitude and the direction of the object must be constant. But when an object is travelling in a circular motion, it keeps on accelerating due to the change in direction, even if its motion is uniform. Quite clearly its velicity won't be constant although, its speed might be.
