If you can ignore friction for a while, then a good example is:
A Golf ball or squash ball rolling on a hardwood floor, like a Basketball court.
A counter example is a disproving of an answer. The counterexample to this is basically your saying if you have two nonzero digits in the tenths place and subtract it, you'll always get a nonzero digit in the answer. but if you have 560.4 - 430.4, then you'll get 130.0. there is a zero in the tenths place. I just disproved that you will always get a nonzero digit in the tenths place. 4 - 4 = 0. the 4s represent the tenths place in each of the 4s in the problem. walah. :P
Velocity has magnitude and direction. Speed just has a magnitude. So without having a direction, the answer to your question is no.
Certainly. For example, a pendulum at its left-most position.
If the velocity changes, the speed may, or may not, change. The velocity can be thought of as having two components: a speed, and a direction. It is possible to change only the direction, for example, when an object moves in a circle at a constant speed. In this case, the velocity changes, but the speed does not.
Velocity is a vector; having direction. So, when changing direction constatly to have velocity a tangent can be drawn to the constantly changing path of the object having velocity.
To draw a picture for velocity, first you need to understand what velocity means. Velocity simply means speed in a given direction. So for a picture you simply need to draw something related to something having speed. For example a ball has speed so you could draw a ball.
On or below the horizontal axis.
It depends on the frame of reference (where it is).On Earth a body on a table is still rotating around the centre of the Earth. This implies a change of direction and thus having a velocity around the centre and an acceleration acceleration due to centripetal force that makes a body follow a curved path. Eben without this the body is orbiting the sun with the same impact
Vector is magnitude and direction. As opposed to scalar having only direction. Example: Velocity Acceleration Applying this to a question could be observeted as the bus moved 40km/h in a East direction.
It will eventually straighten out as it escapes gravity.

All fractions having the form n / (2 * n) where n is a nonzero integer are equivalent to the fraction 1/2. This can actually be generalized to the form x / (2 * x) where x is a nonzero number (e.g. real number, complex number).
