Essays on Gravitational Force

Introduction

Newton's Second Law of motion asserts that the acceleration of an object exhibits a direct proportional relationship with the subsequent force acting on it. It explores the relationship that exists between force, mass and acceleration as exhibited by an object. This experiment examines Newton's Second Law of motion by enabling a dwindling weight to speed up a glider of recognised quantity along a track. A thread that links the dwindling mass to the glider is passed above a smart pulley (Knight, 2004). It is imperative to note that the smart pulley exhibits insignificant inertia, low friction and its revolution ...

Response to Question 1

The height in meters above Sea Level at the Point of observation is 960 meters MSL equivalent pressure MSL equivalent pressure also abbreviated as pMSL pMSL = pobs + pgzobs It is important to acknowledge that p is the density of air at the point of observation and g is the acceleration due to gravitational force and z is the height at the point of observation. In this case, p (density of air at the point of observation) = 1.2041 kg/m3; while g (acceleration due to gravity) = 9.81m/s2. The height in meters (z) at the observation point is 196 meters.

Taking these figures into consideration, pMSL will be attained as indicated below;

pMSL = 1.2041 + ( ...

Gravitational, electromagnetic, strong and weak nuclear forces. Gravitational force is an attraction between any two pieces of matter in the universe. Electromagnetic force is present in pieces of matter, which are able to carry electrical charge. Strong force is holding the nuclei of atoms together. Weak force is responsible for radioactive decay. Molecules are built from the atoms and atoms consist of protons, neutrons and electrons. Protons and neutrons are built of smaller particles called quarks. Electromagnetic spectrum is the range of all the light in the universe. Depending on the wavelength and frequency there are radio, micro, infrared, ...
