Why is difficult to put a cycle into motion then to maintain its motion?
When you first start the cycle, you do work to add kinetic energy to it, which moves if forward, but you are also adding rotational energy to the wheels. Once you are at the desired speed, you only need to overcome frictional forces from air and friction losses in the gears and bearings of the bicycle. If you stop pedaling, the rotational energy of the wheels can help keep it going, for a little while. If you suspend a wheel, and get it spinning, it can spin for a while without any additional input. It takes energy to stop it (some comes from the friction in the bearings to gradually slow it down, and some from the air).
What mechanical motion principle do the brakes in a car or a bicycle use?
Brakes using friction halt or slow down mechanical motion.
What is slow down?
its when something is slowing down
Why does the cyclist have to keep pedalling to maintain their constant velocity?
because the force of friction at the wheels to ground is slowing it down
Which force will slow the rocket down?
an elephant will slow a rocket down
Why would a bike when you stop pedaling continue rolling but start to slow down and eventually stop?
Well that happens because of 2 things:gravity and friction.When you stop pedaling it keeps going because the gravity is causing it to keep going or there is not much friction.It starts to slow down when the friction is enough.
Is it possible to return to the slow down time?
Yes, it is possible to gradually return to the slow down time
