Intermolecular force

no exception to the physical laws of Mother Nature. Friction is a resistive force that always acts in a direction that is opposite to the motion of a body. Frictional forces are dependent on two components; the coefficient of friction and the normal force. Friction = (µ)(n) There are two different types of frictional coefficients, static and kinetic. The coefficient of static friction is the frictional force that must be overcome before any motion commences. It is caused by the minuscule

powerful forces working on the bike and the rider. There is, of course, the downward pull of gravity, friction between the tires and the track, and centrifugal force which acts to the outside of the turn. The key to cornering at high speeds is to perfect the lean angle of the motorcycle so that the force of gravity reaches equilibrium with the centrifugal force attempting to stand the bike back up. If the bike is leaned to far, it falls over. If it is not leaned far enough, centrifugal force pulls it

This paper examines the physics involved in driving a golf ball off the tee. The objective of a drive is to achieve the greatest distance while leaving the golf ball in the middle of the fairway. Several factors will be considered in achieving the longest, and most accurate drive. The factors include calculating the velocity of the golf ball after the club and ball collide, the mass of the club head, launch angle, the shape of the club face, and finding the optimal golf ball. Intuition

securely anchored to the track, which is critical when the cars run through the structure’s twists, turns, loops, and corkscrews. How Roller Coasters Work For the primary duration of a roller coaster ride, a roller coaster is moved only by the forces of inertia and gravity. The only exertion of energy, or rather “work”, occurs at the very beginning of the ride, when the coaster train is pulled up the first hill, which is called the lift hill (Funderstanding Roller Coasters). The purpose of this

gravitational force A= acceleration mu = kinetic friction coefficient · Inertial Forces = m *A · Frictional Force = mu * m * g * cos(theta) · Gravitational Force = m * g * sin(theta) Gravity is the force that

account the resistance of rock bodies to compression and distortion when placed under stress. The ability of a body to resist forces is determined by elasticity. The three moduli of elasticity are: Young's Modulus: E= (Applied force/Area) / (Change in length/original length) Shear Modulus: G= (Applied force/unit area) / (Angular deformation) Bulk Modulus K= (Force/unit area) / (Change in volume/unit volume) Young's Modulus measures the ability of a body to resist elongation or shortening

Throwing a ball in the air is a simple task, but this simple task has many important scientific factors involved. Science plays role in everything we do even if we don’t think about it. Lots of these things are in our lives and we don’t even acknowledge them on a daily basis. We know they are there, but don’t really think about them just let them do their thing. When something is flying through the air the number of factors at work is remarkable. Factors such as weight, wind, mass, and gravity all

situation. When receiving a pass you catch or slow the balls momentum to zero, which is called impulse, the interaction that changes an object’s momentum-a force acting for a time interval (Kirkpatrick Wheeler 107). This is shown in an equation form by, F=P/Dt. By increasing the time over which you decelerate the ball, you lessen the force (Bill Willis 2001). This increase of ‘stopping” time will make it easier to catch and control the ball. Impulse is the same concept in many things like the

Which falling objects fall the fastest? “. Many factors affect the speed of aerodynamics such as the different forces on the object. The aerodynamics of the object and the physics surrounding the object. Great scientists have studied falling objects such as Galileo Galilei and Sir Isaac Newton. I will discuss their lives, experiments and scientific findings. Aerodynamics is the study of force on an object. It has been called the science of flight. Aerodynamics consists of two Greek words. Aerios means
