... Angle is a ratio of two lengths ( = s / r ) so it is unitless. As a convenience we refer to angle as having units of radians, saying, for example, that the angle subtended by half a circle is radians, but this is a notational convenience. Angle is dimensionless. Speed is the rate of change of s; ...

Getting to Know: Speed, Velocity, and Acceleration
... like friction, acts upon that object. This law is commonly called the law of inertia. Newton’s Second Law of Motion states that objects will accelerate when a force acts upon a mass. In this law, we learn that there is a relationship between the mass of an object and the amount of force required to ...

... Note that changing the integration interval for fi from [0, 1] to [1, 0] is equivalent to having the particle decelerate. This changes the sign of the ith particle’s contribution to (I.5), just as the sign of its contribution to the soft factor would switch. Here, I have shown that the result discus ...

Various planetary models described the motion of planets in circles before any understanding of gravitation. The motion of the moon around the earth is nearly circular. The motions of the pl ...
