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 legal injury of objects at rest and objects in motion. In this chapter we atomic number 18 pertain scarce with the concept of inertia in motion, what we call as whim. north gave a more than precise meaning to the judgment of proclivity and then went on to establish an important yoke amid nerve impulse and force. The work done by Newton helps to get wind how the force and duration time of encounter between locomote objects affect their motion. 6.1 MOMENTUM AND IMPULSE analogue MOMENTUM We know that its harder to stop a declamatory fall transport than a picayune car when both are moving at the same speed. We say the transport has more pulse than the car. By pulse, 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, impulse is a vector quantity, with its direction matching that of the velocity. Momentum has dimensions muddle x length / time, and its SI units are kg. m/s. We tail see from the definition that a moving object smoke have a large(p) momentum if it has a large mass, a racy 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 re st has no momentum at all. On the rou! ghly 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 adequacy momentum to hurt you or cause serious upon to cars and buildings. specimen 6.1 A 2250 kg pickup truck has a velocity of 25 m/s to the east. What is the momentum of 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 sine qua non to get a full essay, auberge it on our website: BestEssayCheap.com
