1) Define “centripetal force”. How is it related to “centrifugal force”? Centripetal force is the force that keeps objects moving at a uniform speed along a circular path. This is directed along a circle's radius, towards the center of the circle away from the object. Centrifugal force is the lack...

Question One The equation derived in the lab manual is hereby recalled as; a=(F_M-F_m)/(M+m) =(Mg-mg)/(M+m) =[(M-m)/(M+m)]g Therefore to determine whether this equation makes sense, we will equate each of the masses to zero. Experimentally, when one mass is equated to zero, say, by removing all the pennies in one mass,...

Isaac Newton first published his Universal Law of Gravity in the journal, Philosophiæ Naturalis Principia Mathematica, in July of 1687. The story goes that one day, Newton was sitting underneath an apple tree when an apple suddenly fell to the ground. He considered the problem with this, wanting to understand...

Theory The primary aim of this lab is to determine the correlation that exists between centripetal force, mass, and velocity of an object that is experiencing centripetal acceleration. The object will always be changing direction while maintaining its movement in its circular path. Centripetal force is the term used to...

Question 1 According to Newton’s First law, a body will remain in a state of rest or uniform motion, unless it is acted upon by an external force (“S-Cool, the revision website). In this case, the mass is in an uniform motion which means that there is no acceleration. Since...

X-ray are classified and outlined as an electromagnetic type of waves. They transmit high energy hence can pass through molecular substance. As a result, the energy makes them critical especially when it comes to medical applicability. More importantly, the waves find high usability in industrial processes especially in packaging of...

From the analysis of this lab, we can conclude that the impulse-momentum theory is correct. One way to compare the values of the launch portion and the landing portion was finding the percentage difference multiplied by 100%. Percentage wise the error was 1.5%. The values were close undoubtedly proving the...
