Who invented circular motion? Newton Why is circular motion important in our daily lives? Circular motion is very common and very important in our everyday life. Satellites, the moon, the solar system and stars in galaxies all rotate in “circular” orbits. The term circular here is being used loosely since even repetitive closed motion is […]
What comes first in trace conditioning?
What comes first in trace conditioning? a procedure in classical conditioning in which a conditioned stimulus and an unconditioned stimulus are separated by a constant interval (called the trace interval), with the conditioned stimulus presented first.

Why is surface topography important?
Why is surface topography important? Surface topography refers to both the profile shape and the surface roughness (including the waviness and the asperity or the finish). Surface topography affects the film thickness to roughness ratio and the lubrication regime. These interactions become more important as the thickness-to-roughness ratio reduces. What is topography material? The topography […]
