A seismograph, or seismometer, is an instrument used to DETECT and RECORD earthquakes. Generally, it CONSISTS of a mass attached to a fixed base. During an earthquake, the base moves and the mass does not. The motion of the base with respect to the mass is COMMONLY transformed into an electrical voltage.

th's axis SLOWLY precesses, always making an angle of 23.5° with the direction perpendicular to the PLANE of EARTH's orbit. The change in angular momentum for the two shown positions is QUITE large, although the MAGNITUDE L is unchanged.

The kilogram-force (kgf or kgF), or kilopond (kp, from LATIN: pondus, lit. 'weight'), is a non-standard gravitational metric unit of force. It is equal to the magnitude of the force EXERTED on one kilogram of mass in a 9.80665 m/s2 gravitational field (standard gravity, a conventional value approximating the average magnitude of gravity on EARTH).[1] That is, it is the weight of a kilogram under standard gravity. Therefore, one kilogram-force is by definition equal to 9.80665 N.[2][3] Similarly, a gram-force is 9.80665 mN, and a milligram-force is 9.80665 μN.

Gravity is arguably the first force that people really learn about. People don't really think of it as learning about gravity because it is such a big part of our everyday lives. Babies learning to crawl or walk are STRUGGLING against gravity, games involving jumping, climbing or balls all give people a sense of the effect of gravity. The saying “everything that goes up, must come down” is all about gravity. Rain falls from the sky because of gravity and so much more. We all know that these things happen but we don't often stop to ask what is gravity, what causes it and how can we describe it more accurately than “everything that goes up, must come down”? All of the examples mentioned involve objects with mass falling to the GROUND, they are being attracted to the Earth. Gravity is the name we give to the force that arises between objects because of their mass. It is always an ATTRACTIVE force. It is a non-contact force, therefore it acts at a distance. The Earth is responsible for a gravitational force on the MOON which keeps it in its orbit around the Earth and the gravitational force the moon exerts on the Earth is the dominant cause of ocean tides. Sir Isaac Newton was the first scientist to precisely define the gravitational force, and to show that it could explain both falling bodies and astronomical motions. The gravitational force is relatively simple. It is always attractive, and it depends only on the masses involved and the distance between them. Stated in modern language, Newton’s universal law of gravitation states that every particle in the universe ATTRACTS every other particle with a force along a line joining them. The force is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.Hope it help Please mark it brainelis

Types Of Friction Static Friction Sliding Friction ROLLING Friction Fluid Friction Static Friction Static friction is defined as the frictional force that acts between the surfaces when they are at REST with respect to each other. The magnitude of the static force is EQUAL in the opposite direction when a small amount of force is applied. When the force increases, at some point maximum static friction is reached. Static Friction Examples Skiing against the snow Creating heat by rubbing both the HANDS together Table lamp resting on the table Coefficient Of Static Friction The coefficient of static friction is denoted as µs. The maximum force of static friction is given as the product of the coefficient of static friction and normal force and force of static friction is less than or equal to the product of the coefficient of static friction and normal force. It is given as:                                   Fs max = µs η and Fs ≤ µs η Where, Fs is the force of static friction µs is the coefficient of static friction η is the normal force Fs max is the maximum force of static friction What Is Sliding Friction? Sliding friction is defined as the resistance that is created between any two OBJECTS when they are sliding against each other. Examples Of Sliding FrictionSliding of the block across the floor Two cards sliding against each other in a deck Coefficient Of Sliding Friction The coefficient of sliding friction is denoted as µs. The force of sliding friction is defined as the product of the coefficient of sliding friction and the normal force. It is given as:                                           Fs = µs. Fn What Is Rolling Friction? Rolling friction is defined as the force which resists the motion of a ball or wheel and is the weakest types of friction. Examples Of Rolling Friction Rolling of the log on the ground Wheels of the moving vehicles Coefficient Of Rolling Friction The coefficient of rolling friction is denoted as µr. The force of rolling friction is defined as the product of the coefficient of rolling friction and the normal force. It is given as:                                             Fs = µr. Fn What Is Fluid Friction? Fluid friction is defined as the friction that exists between the layers of the fluid when they are moving relative to each other. Examples Of Fluid Friction The flow of ink in pens Swimming

tance-RATE-Time Problem LSC-O 6/2010, Rev. 1/2011 1 of 2 Instructions Example 1. Carefully read the problem, note what numerical data is given, and what is being asked for. Two airplanes depart from an AIRPORT simultaneously, one flying 100 km/hr faster than the other. These planes travel in opposite directions, and after 1.5 hours they are 1275 km apart. Determine the speed of each plane. 2. Make a sketch, drawing, or picture of the described situation, and put all the given data from the problem on the drawing. Look for what the problem’s question is. In other words, what do they want to know? In this example, the problem asks you to find the speed of each plane. Let X = the speed of one plane, and y = the speed of the other. 3. Write down any numerical relationships that the problem gives you: Distance apart is 1275 km, time traveled is 1.5 hrs, and one plane is traveling 100 m/hr. faster than the other. Let plane X be the faster plane. 4. Look for other information (numbers, formulas, etc.) that you can use to relate all the items. Distance = Rate • Time is the formula you need in this case. Distance traveled = Rate (or Speed) times Time. 1275 km is the total of the DISTANCES (added together) that each plan travels. Travel time for each plane is the same, 1.5 hours; however, the planes’ speeds differ by 100 km/
