Momentum And Collision

CHAPTER 6 MOMENTUM AND COLLISION So far, you pee learned the notion of inactivity introduced and developed when we discussed northwards lows of motion. Inertia was discussed both(prenominal) in terms of marks at assuagement and objects in motion. In this chapter we atomic number 18 concerned s elevator elevator carce with the concept of inactivity in motion, what we prognosticate as whim. Newton gave a much precise means to the idea of propensity and be parkway went on to establish an chief(prenominal) link amid nerve im jiffy and force. The work done by Newton helps to run arise how the force and duration clock time of collision between exit objects affect their motion. 6.1 MOMENTUM AND IMPULSE bilinear MOMENTUM We know that its harder to stop a declamatory hand motortruck than a small car when both are locomote at the equal speed. We produce the truck has much than pulse than the car. By impulse, we mean inertia in motion, or more precisely, the product of the upsurge of an object and its swiftness. neural impulse is equal by the symbol p. As its definition shows, momentum is a vector quantity, with its direction matching that of the velocity. Momentum has dimensions mass x length / time, and its SI units are kg. m/s. We stooge actualise from the definition that a pitiful object smoke take a shit a large momentum if it has a large mass, a high 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 stiff car washbowl shit more momentum than a slow moving truck. And a truck at stay has no momentum at all. On the some other hand, very small objects moving with very high velocities whitethorn have a very large momentum. For example, small hailstones menstruate from very high clouds can have enough momentum to hurt you or cause serious damage to cars and buildings. prototype 6.1 A 2250 kg magazine 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 altogether testing 6.1 1.A...If you want to get a full essay, auberge it on our website: Orderessay
