' uniform motion in a circle in which speed is constant but velocity is changing'?
This is because the term "velocity" includes a specification both of a speed, and a direction. The direction changes, therefore the velocity changes.
What is 20 miles per hour north an example of?
A velocity vector includes both speed and direction.
Can a body have a uniform speed having an acceleration?
Yes a body can have both a uniform speed and an acceleration. This is because speed is a scalar quantity, meaning it does not depend on direction. Acceleration is a vector quantity, meaning it does depend on direction. This means that when you are changing direction you are accelerating in that direction. During this time your speed may remain constant. Think about taking a turn in a car. You can put on enough gas to keep you at 20 mph but you are still changing direction so you are accelerating.
What do you mean by vectare Quantity give example?
A vector quantity refers to a physical quantity that has both magnitude and direction. Some examples of vector quantities include velocity (speed and direction), force (magnitude and direction), and displacement (distance and direction).
20 miles per hour north is an example of?
This measure is an example of velocity, which includes both a speed and a direction.
