Question

can a body have a constant speed and still have varying velocity? Explain with an example.

Answer 1

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.

Answer 2

Yes,since speed is the distance travelled by a body per unit time and velocity is the distance travelled by a body per unit time in a given direction.further ,velocity (displacement)can be changed by changing its magnitude or direction . For example,if a body travels from a to b(6km) and then back to a(6km) it's distance will be 12km (6+6km)but it's velocity or displacement will be zero
