Cracks forming in a boulder aka erosion.
In waveform physics, constructive and destructive interference describes the way two different waves interact with one another. If two waves are aligned such that the peaks of both are in the same spot, the waves experience constructive interference - the two add together and become a single, more powerful wave. The opposite happens if the peak of one meets the trough of the other - the two cancel each other out, and the magnitude of the combined wave is lesser than the individual waves. There are also other, more complex versions of interference if they don’t align cleanly, but the most common descriptions of interference are the ones described above.
Hope this helps!
A. Direction
Speed is just distance divided by time, but velocity is displacement divided by time and displacement has direction. Speed will always be positive, but velocity can be either positive or negative.
Answer:
Friction produces unnecessary heat leading to the wastage of energy. The force of friction acts in the opposite direction of motion, so friction slows down the motion of moving objects. Forest fires are caused due to the friction between tree branches. However, friction can also cause problems in a car. Friction between moving engine parts increases their temperature and causes the parts to wear down. Friction can be both harmful and helpful, so it may be necessary to decrease or increase friction.
