Question

IN UNIFORM CIRCULAR MOTION, WHY DOES THE VELOCITY CHANGE EVEN IF THE SPEED IS CONSTANT ?

Answer 1

velocity is a vector, meaning it has a magnitude (size) and a direction. To change a vector, you can change the size or you can change the direction,or you can change both. When traveling in a circle at constant speed, you are only changing the direction, but that still changes the vector

Answer 2

When you are making a left turn your body seems like it wants to lean to the right . what causes your body to want to lean to the right ?

Answer 3

what's really happening is your body wants to continue moving in a straight line... the car is going left under you which makes you think you are going right

Answer 5

Circular motion have a particular acceleration: the centripetal force, even the uniform ones are affected by that. The formula: \[v² \over r\]
