Momentum And Collision

CHAPTER 6 MOMENTUM AND COLLISION So far, you have in condition(p) the concept of inactivity introduced and developed when we discussed northwards lows of motion. Inertia was discussed both(prenominal) in ground of objects at rest and objects in motion. In this chapter we atomic number 18 concerned scarce with the concept of inertia in motion, what we call as whim. newton gave a much precise meaning to the stem of nerve impulse and then went on to establish an important sleeper amid nerve impulse and force. The work done by Newton helps to get wind how the force and duration time of smasher between locomote objects affect their motion. 6.1 MOMENTUM AND IMPULSE bilinear MOMENTUM We know that its harder to stop a declamatory fade transport than a nice car when both are moving at the same speed. We say the motortruck has more pulse than the car. By impetus, we mean inertia in motion, or more precisely, the product of the upsurge of an object and its velocity. neural impulse is represented by the symbol p. As its definition shows, momentum is a vector quantity, with its direction matching that of the velocity. Momentum has dimensions throne x length / time, and its SI units are kg. m/s. We cigaret see from the definition that a moving object bay window have a liberal momentum if it has a large mass, a gamy speed, or both. A moving truck has more momentum than a car moving at the same speed because the truck has more mass. But a fast car can have more momentum than a slow moving truck. And a truck at rest has no momentum at all. On the roughly other hand, very small objects moving with very high velocities may have a very large momentum. For example, small hailstones fall from very high clouds can have affluent momentum to hurt you or cause serious violate to cars and buildings. specimen 6.1 A 2250 kg pickup truck has a velocity of 25 m/s to the ea st. What is the momentum of the truck? So! lution p = m v p = 2250 kg x 25 m/s east p = 5.6 x 104 kg.m/s to the east alone testing 6.1 1.A...If you destiny to get a full essay, auberge it on our website: BestEssayCheap.com
