i) Can a body have a constant speed and still have a varying velocity? (ii) Can a body have a constant velocity and still have a varying speed?
(1)
let us talk about it in simple terms vector quantity- are the quantities which have magnitude & direction-velocity is a vector quantity because it has both scaler quantity- are the quantities which have magnitude but do not have the direction- speed is scaler because it has the magnitude but do not have the direction so if the speed is constant & object keeps on changing the direction then velocity will keep on changing , like if you rotate an object tied with rope at one end at constant speed,since the direction is cganging contineously so does the velocity
(2)
No, in order for the velocity to be constant, the speed has to be constant. Speed is a scalar, meaning that it is just a number. (A car goes 50 miles per hour). Velocity is a vector, which indicates that it needs a measure of its displacement and a direction. (A car is going 50 mph to the east). A body can have a constant speed but a changing velocity because the direction can change while the speed is constant. (A car goes 50 mph around a roundabout). However, a body can not have a constant velocity with a changing speed. A car can not be slowing down yet still be going the same speed and direction.
