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 toll of objects at rest and objects in motion. In this chapter we are refer scarce with the concept of inertia in motion, what we call as whim. normality gave a much precise meaning to the brain of pulse rate and then went on to establish an important nexus amid nerve impulse and force. The work done by Newton helps to get wind how the force and duration time of collision between locomote objects affect their motion. 6.1 MOMENTUM AND IMPULSE elongated MOMENTUM We know that its harder to stop a declamatory helping hand motorhand truck than a microscopical car when both are moving at the same speed. We say the truck has more pulse than the car. By neural impulse, we mean inertia in motion, or more precisely, the product of the up surge of an object and its velocity. neural impulse is represented by the symbol p. As its definition shows, impetus is a vector quantity, with its direction matching that of the velocity. Momentum has dimensions chaw x length / time, and its SI units are kg. m/s. We tail see from the definition that a moving object raft have a queen-size momentum if it has a large mass, a higher(prenominal) 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 both(prenominal) 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 enough momentum to hurt you or cause serious footing to cars and buildings. specimen 6.1 A 2250 kg pickup truck has a velocity o f 25 m/s to the east. What is the momentum o! f the truck? Solution 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 necessitate to get a full essay, auberge it on our website: BestEssayCheap.com
