For example, an object thrown upwards, when it is at its highest point. This situation is only possible for an instant - if the acceleration is non-zero, the velocity changes, and can therefore not remain at zero.
One example of Velocity is that if you are running in the same direction, your speed and velocity is the same. But if you are running AROUND the track, your speed is the same but your velocity is changing.
non-examples are like just like going straight in the road.
average velocity=displacement/total time taken
Speed is a scalar (non-directional) representation of velocity. Friction affects the magnitude of both and the direction of velocity.

No. ME isn't capable of understanding this. Feisty with Beryl, OTOH....
Non uniform velocity is known as variable velocity.
It is an example of a velocity.
An object moving in a circular path at constant speed will have a non-zero average speed and zero average velocity since velocity is a vector parameter,
The velocity of a cube is _?
Yes, but it will have a non-zero velocity afterwards.
Throwing a ball straight up in the air. It will reach some peak where the velocity is zero, but the acceleration due to gravity is a constant -9.8m/s^2.

That simply means that its velocity is changing.
Yes. A non-zero force may not be sufficient to alter the velocity - for example if it is smaller that the limiting friction. No change in velocity implies no change in momentum and so impulse = 0.
An object's velocity is it's speed plus direction. example: 55mph south Hope this helps:)
