“THE EFFECT OF AIR RESISTANCE WITH RELATIONSHIP TO THE AREA OF THE PAPER IN FREE FALL MOTION” An Investigatory Project I-INTRODUCTION A. Background of the Study When an object is dropped‚ the force of gravity will cause it to speed up as it falls. But friction with the air‚ called drag‚ will tend to cause it to slow down. How much drag there is depends mostly on two factors: speed and shape. The faster an object moves through

Newton’s Laws First let’s get to know some history about the man behind all of this‚ Sir Isaac Newton. Sir Isaac Newton‚ the man who is responsible for what we all have come to know as the “Laws of Motion” was born on January 4‚ 1643‚ which is very often displayed as December 25‚ 1642‚ if using the older version of the Julien calendar‚ in the Helmet of Woolsthorpe‚ England. Sir Isaac Newton is believed to be one of the most influential scientists known to have ever lived. His ideas became the basis

How Sugar Affects the Body in Motion By GRETCHEN REYNOLDS Gary John Norman/Getty Images Sugar is getting a bad reputation. A cover article in The New York Times Magazine several weeks ago persuasively reported that our national overindulgence in fructose and other sugars is driving the epidemics of obesity‚ diabetes and other illnesses. But that much-discussed article‚ by the writer Gary Taubes‚ focused on how sugars like fructose affect the body in general. It had little opportunity to examine

EXERCISE 8 - Rotational Dynamics‚ Equilibrium of rigid body 1. If the torque required to loosen a nut that is holding a flat tire in place on a car has a magnitude of 40.0 N m‚ what minimum force must be exerted by the mechanic at the end of a 30.0-cm lug wrench to accomplish the task? 133 N 2. A steel band exerts a horizontal force of 80.0 N on a tooth at point B in Figure 1. What is the torque on the root of the tooth about point A? 0.64 Nm 3. Calculate the net torque (magnitude and

will travel ? Exploring Newtons 2nd Law of motion. Background Research How does changing the mass of an object effect how far it will travel ? This question can be answered by Newtons 2nd law of motion; Force equals mass multiplied acceleration (F= ma). This law states that a force on an object will cause it to accelerate in the direction of the force. The greater the force exerted on the object‚ the greater the acceleration. But how does mass effect this ? To find out‚ an experiment will be

If the Earth actually spun on an axis (as required in a heliocentric system to explain the diurnal motion of the sky)‚ why didn’t objects fly off the spinning Earth? 2. If the Earth was in motion around the sun‚ why didn’t it leave behind the birds flying in the air? 3. If the Earth were actually on an orbit around the sun‚ why wasn’t a parallax effect observed? That is‚ as illustrated in the adjacent figure‚ stars should appear to change their position with the respect to
