the above Answer: B Diff: 1 Topic: Galileo’s Concept of Inertia 3) Galileo said that if you rolled a ball along a level surface it would A) slow down due to its natural tendency to come to rest. B) keep rolling without slowing down if no friction acted upon it. C) roll as long as its inertia nudged it along. D) roll in the opposite direction. Answer: B Diff: 1 Topic: Galileo’s Concept of Inertia 4) When Galileo rolled a ball down an incline and up another incline‚ he found that

People sometimes engage in activities and are unaware that such activity involves physics. Physics is all around. For instance‚ you may go to Six Flags and do not analyze how physics helps the machines you ride in operate. Have you ever asked yourself how a roller coaster works? Would roller coasters safely run without the knowledge that physics offers us? The answer is no. Roller coasters are driven by physics; it mobilizes and gives its riders amusement through forces such as inertia‚ gravitation

liquid exhibits this resistance to some degree. Therefore the more resistance shown‚ the higher the viscosity. It can be thought of as fluid friction‚ just as solids show friction between other solids. This friction is caused by the molecules within the substance. Viscosity is dependent on many variables of which include: temperature‚ density‚ concentration‚ friction‚ and gravity. The biggest factor of viscosity is by far temperature. By varying the temperature you can change the viscosity of just about

momentum? What is their difference in kinetic energy? 2. A 12 g bullet is fired horizontally into a 96 g wooden block initially at rest on a horizontal surface. After impact‚ the block slides 7.5 m before coming to rest. If the coefficient of kinetic friction between block and surface is 0.60‚ what was the speed of the bullet immediately before impact? You have to use the conservation of the total energy of the system to do this problem: Initially‚ you have‚ in the total of your system‚ a bullet

Leading Marines is the greatest resource that I have come across so far for guidance and motivation in becoming a leader of Marines. In one neat sentence located in the forward‚ we are given everything that sums up what is expected of future leaders of Marines: "Our actions as Marines every day must embody the legacy of those who went before us." Marines have a great expectation to live up to‚ and as commissioned officers we must absolutely carry on the tradition of excellent leadership that has

Experimental Research of Wear On Filled PTFE Alloy Bearings ABSTRACT: Because of the lower coefficient of friction and good strength to weight ratio features polymer based composites are frequently used. In this work‚ experimental investigations were conducted on wear behavior of PTFE composite radial bearings filled with 15% glass fiber (GF15)‚ 40 % bronze (B40) and 35% carbon (C35) where bearing loads‚ sliding distances and wear were taken into account. For the fact that pivot pins have their

collision? A 50-kg cart moving at 100 km/h collides head-on with an approaching 50-kg cart moving at 10 km/h (in the opposite direction). If the two carts stick together‚ what will be their speed? A 30-kg girl and a 50-kg boy face each other on friction-free roller skates. The girl pushes the boy‚ who moves away at a speed of 3 m/s. What is the girl’s speed? A 70-kg free-floating astronaut fires 0.10-kg of gas at a speed of 30 m/s from her propulsion pistol. What is the astronaut’s recoil speed
