yields two integrations: x = x0+v0t+1/2at2 v = v9+at These two expressions show the relationship between position‚ velocity‚ and acceleration at a given time. Newton’s 2nd law states that the acceleration of an object depends on the net force acting upon the object and the mass of the object. If there were no friction in this experiment‚ then the acceleration of the glider would be equal to acceleration of gravity multiplied by the angle between the air track and the horizontal table (g

Physics notes Force is an agent which produces or tends to produce motion in an object‚ stops or tends to stop ‚ motion of an object Newton’s 1st law of motion: If an object is at rest‚ will remain at rest until or unless an external force act on it. If an object is in motion ‚ it continues its motion until or unless an external force act on it Newton’s 1st law of motion is also called first law of inertia. Inertia: The tendency of an object to resist any change in its state of motion

destructive. Not all conflict is a destructive force in our lives. Conflict is more of a constructive force that results in building something new no matter how bad the outcome of conflict. If conflict were to be a destructive force then society would fail to advance to the world today‚ instead we would live in a world of anarchy. The type of construction that arises from conflict is the reason why the world is the way it is today. Conflict provides a force that constructs people and the way they think

In any organization‚ a clear-cut hierarchy of personnel is necessary to ensure that things run smoothly at all levels. The armed forces is no exception. For thousands of years‚ military forces worldwide have maintained a strict structure of rank to ensure smooth operations and the maintenance of order in stressful environments. In fact‚ rank structure is one of the most defining characteristics of an organized military and serves a number of purposes. In order to build and maintain this discipline

affects how much centripetal force affects an object. Centripetal force plays a major part in every day life. This force is the reason for the sensation of being ‘pushed’ into the car door that passengers in a car feel when the driver makes a sharp left turn (The Centripetal Force Requirement‚ n.d.). It is the reason people feel almost weightless on rollercoasters‚ and on an even larger scale‚ it is what keeps the moon orbiting around Earth. Without centripetal force‚ cars would not be able to make

there is a constant relationship between these forces. Lift is the upward force created by the effect of airflow as it passes over and under the wing. The airplane is supported in flight by lift. Weight‚ which opposes lift‚ is caused by the downward pull of gravity. Thrust is the forward force which propels the airplane through the air‚ which varies with the amount of engine power being used. Opposing thrust is drag‚ which is a backward‚ or retarding‚ force which limits the speed of the airplane. I’m
