chapter 10 - School of Physics
... Physics is the most fundamental of all sciences. Physics is also the foundation of much modern technology, from maglev trains to hip replacements, from CDs to sunglasses, from light bulbs to carbon-dating. Physics ranges from the very large (the universe) to the very small (the quantum world) and ev ...

introduction and basic concepts
... A system is defined as a quantity of matter or a region in space chosen for study. The mass or region outside the system is called the surroundings. The real or imaginary surface that separates the system from its surroundings is called the boundary. Discussion Some authors like to define closed sys ...

... UK, small amounts of liquid plastic are injected into the sewage system. The plastic particles mix with the sewage particles, reducing the liquid’s viscosity and adhesion to the sewer pipe and walls, and thereby making it easier for the pumps to transfer the sewage. A similar method can be used to r ...

Physics, Chapter 10: Momentum and Impulse
... motion of a particle when acted upon by a force. Suppose we consider a stream of particles of mass m, each moving with velocity v, that strike a target and come to rest in it, and inquire about the average force exerted on the target to hold it in place. From another point of view we may ask what fo ...

MECHANICAL PRINCIPLES OUTCOME 4
... Consider a block on an inclined plane at angle φ to the horizontal. The weight acts vertically downwards. This must be resolved into two components parallel and perpendicular to the plane. Resolving R = W cos α and F1 = W sin α If no other force is involved then the block will slide down the plane i ...

Static and Kinetic Friction
... There are two types of frictional forces, static and kinetic. Static friction is what keeps a resting body at rest. Kinetic friction is what slows down an object when slid on a surface. Any two materials have a static and kinetic coefficient of friction which represents how much friction exists when ...

A skeleton runner in the Winter Olympics drops 104 m in elevation from top to bottom of the run. a) In the absence of nonconservative forces, what would the speed of a rider be at the end of the track. Assume initial velocity of zero. b) In reality, the best riders reach the bottom at a speed of 35. ...
