DYNAMICS -studies the relationship of motion to the forces that causes it. Types of Forces: (a) Normal Force‚ n :When an object rests or pushes on a surface‚ the surface exerts a push on it that is directed perpendicular to the surface. (b) Friction Force‚ f : In addition to the normal force‚ a surface may exert a frictional force on a object‚ directed parallel to the surface and opposite the motion or impending motion of the object. f s = µ s n - static friction‚ maximum friction before the object

Laws of Motion and Thermodynamics The first example is oscillating a pendulum‚ which is categorized in the law of motion due to the object remaining in that state unless an external force is applied. The second example stating cooling food and drinks in a refrigerator is categorized in the laws of Thermodynamics due to thermalization. The third example of using the coffeemaker can be a combination of both laws due to moving touching to coffeemaker to make create an action is Law of Motion‚ however

AIR-STANDARD ANALYSIS: INTERNAL COMBUSTION ENGINES Air-standard analysis treats the fluid flow through the entire engine as air and approxi¬mates air as an ideal gas. In a real engine inlet flow may be all air‚ or it may be mixed‚ up with 7% fuel‚ either gaseous or as liquid droplets‚ or both. In air-standard analysis‚ even if all fluid in an engine cycle were air‚ some error would be introduced by assuming it to be an ideal gas with constant specific heats. At the low pressures of inlet and

In June 6 our world are shocks with increasing price of oil‚ $140 for a barrel. This wills effect the economic growth around the world because oil is the major source of energy. Good and service that need oil to transport from firm to consumer. So a little increasing price of oil will lead to higher price of good and service. Recently the oil price is keeping increasing. Crude oil climbed more than $10 to $138.54 a barrel. The increasing of oil price is crucial to keep the demand low and sustain

Experiment 3.1 Newton’s Second Law of Motion Aim: To investigate the relationship between net force‚ mass and acceleration Hypothesis: Since Newton’s second law of motion states that the acceleration of an object is directly proportional to the total force acting upon that object‚ we can assume that the more mass being pulled down on the cart the greater the acceleration of it will be and therefore the greater its net force will be. Apparatus: Wheeled carts Pulleys Balance

In 1687‚ Sir Isaac Newton published what are known today as Newton’s three laws of motion. If these laws didn’t exist‚ motion and life would not exist. His three laws are accurately relative to what "normal" speeds are on earth. Newton’s first law is most commonly referred to as the law of inertia. The law states that an object that is at rest will stay at rest unless an unbalanced force acts upon it‚ and vice-versa. If an object is moving and there is no force to move the object in a different

E104: NEWTON’S SECOND LAW OF MOTION METHODOLOGY In Part A of the experiment (Constant Mass‚ Changing Net Force)‚ place the dynamics track on the laboratory table. Make sure that it is horizontal by placing the dynamics cart on the track. If the dynamics cart does not move‚ then the track is already horizontal. Otherwise‚ make the necessary adjustments. Get the mass of the dynamics cart. Write this under m1 in Table 1. Set the first photogate at the 20-cm mark of the dynamics track and the second
