scientific revolution of the 17th century. With discoveries in optics‚ motion and mathematics‚ Newton technologically advanced the principles of modern physics. In 1687‚ he distributed his most commended work‚ Philosophiae Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy)‚ which has been named the single most influential book on physics. His work compromises an exact quantitative explanation of bodies in motion in three basic laws: 1) A unmoving body will stay stationary unless

Abstract In this experiment Newton’s Second Law of Motion was measured with the use of the gravitational acceleration g on Earth by applying a free fall process. Objective The objective of this experiment is to validate Newton’s Second Law of motion. In experimenting the Law the measurement of acceleration of gravity was used by measuring the distance a dropped ball travels for a specific amount of time. Procedure First‚ measurements were taken of the distance from the stairway

projectile motion is motion in two dimensions in both X & Y directions. The only force on the projectile is gravity. With gravity being a presence and a factor in our everyday lives and in this experiment‚ gravity will push down on the projectile forcing it back down to the ground. For example if someone shot a cannon straight and there was no gravity then the cannon would keep traveling at a constant speed‚ go farther and travel in a straight line. Note this is Newtons first law about motion‚ an object

distance x measured along the arc. If the motion is simple harmonic‚ the restoring force must be directly proportional to x or to θ because x=L θ. The restoring force F is the tangential component of the gravity. The restoring force is proportional not to θ but sin θ‚ so the motion is not simple harmonic. However‚ if the angle θ is small‚ sin θ is very nearly equal to θ (in radians). Thus we have: The bob will then execute simple harmonic motion and x (or θ) will be a sinusoidal function

go take a look at the first one. As you just saw in this Polo segment‚ Newton’s first law is one of the reason this game exists‚ if you hit the ball with the polo sick the reason for the ball to continue in motion is because of Newton’s First Law‚ “An object in motion will remain in motion unless an external force acts upon it.” But the reasons behind the ball slowing down is because of the outside forces‚ those are acting on the ball‚ causing the ball to slow down. Let’s go take a look at the

an English Physicist‚ Sir Isaac Newton is one of the most powerful personality who first introduced the laws of gravitation. He was born on January 4‚ 1643A.D. in Woolsthorpe‚ Lincolnshire of England who later introduced the three important laws of motion and universal gravitation‚ explored the laws of optics and is also known as the creator of Calculus. In 1687 A.D.‚ He wrote all his works during his works during his time in Philosophiae Naturalis Principia Mathematicia (Mathematicial Principles of

would be the only force acting on the object. But in the atmosphere‚ the motion of a falling object is opposed by the air resistance or drag. The drag equation tells us that drag is equal to a coefficient times one half the air density (R) times the velocity (V) squared times a reference area on which the drag coefficient is based. The motion of a falling object can be described by Newton ’s second law of motion‚ Force = mass x acceleration. Do a little algebra and solve for the acceleration
