Without a third part the question it is almost impossible to answer. The answer could be as simple as 1 Mississippi as a form of measuring time.
the simple answer is they vibrate. / as you "bake" the molecules they gain velocity and cause friction, which we humans perceive as heat.
A body moving at a uniform speed may have a uniform velocity, or its velocity could be changing. How could that be? Let's look. The difference between speed and velocity is that velocity is speed with a direction vector associated with it. If a car is going from, say, Cheyenne, Wyoming to the Nebraska state line at a steady speed of 70 miles per hour, its velocity is 70 miles per hour east. Simple and easy. Uniform speed equals uniform velocity. (Yes, I-80 isn't perfectly straight there. Let's not split hairs.) But a car moving around a circular track at a uniform speed is constantly changing direction. Its speed is constant, but its velocity is changing every moment because the directionit is going is changing. Speed is uniform, but velocity isn't. As asked, uniform speed is a uniform distance per unit of time. And this will yield a uniform distance per unit of time in its velocity, but the direction vector may be uniform or it may be changing each moment, as illustrated.
The velocity reaches a maximum, and the pendulum will begin to decelerate. Because the acceleration is the derivative of the velocity, and the derivative at the location of an extrema is zero, the acceleration goes to zero.
Increase current by either increasing the voltage or decreasing the resistance.
A parallax bar or stereometer is a simple measuring device that is used to determine the height of objects in photographs.
Simple, velocity = distance by time ,which probably means distance = velocity X times.
Simple - look up escape velocity on wikipedia
Momentum is a simple product of mass time velocity. So if the velocity doubles the momentum doubles.

the speed of motion is determined by how fast the object in motion is traveling along with the distance it has traveled. the direction of motion can be discovered by either using a frame of reference (point of comparison) or simple devices such as a compass.
Velocity's' symbol is represented by a simple: "V".
Pulleys are simple machines.

There are several, what is it that you want to calculate? The "natural" units for angular velocity are radians/second. The relationship between linear velocity and angular velocity is especially simple in this case: linear velocity (at the edge) = angular velocity x radius.
by increasing the distance.
However you like. For some things distance does not vary at all - or not measurably so eg between London and New York. For objects under simple harmonic motion (such as a pendulum) the distance increases and decreases (according to quite a simple formula). For the archetypal drunken walk (or Brownian motion) the distance is random.
