It's the movement of a object along the circumference of a circle or the rotation along a circular path.
From what I have been told, the four basic forces regarding physics are the strong or powerful force, a gravitational force, an electromagnetic force, and a weak force. The strong force binds nuclei. Weak forces take care of nuclear decay. Electromagnetic forces exists when two or more objects have an electric charge like a magnet or positive and negative, negative and positive And gravitational forces is just gravity. What holds us down.
Momentum = (mass) x (speed)
Momentum = (12,000 kg) x (40 m/s)
Momentum = (12,000 x 40) kg-m/s
<em>Momentum = 480,000 kg-m/s </em>
The fastest nerve signals travel at speeds that exceed 100 meters per second :)
<span>When sound waves travel from air into water, they'll immediately
start moving faster. (Their speed will increase.)
Of course, this means that although their frequency won't change,
their wavelength will increase.</span>
