Impulse and momentum Study guides, Class notes & Summaries

PHY-102: Energy and Circular Motion Exercises Questions and answers Complete the following exercises. 1. A rifle with a longer barrel can fire bullets with a larger velocity than a rifle with a shorter barrel. a. Explain this using the impulse-momentum theorem. By the theory of momentum, change in momentum of an object equals the impulse applied to it meaning that the long barrel of the rifle covers a huge amount of motion of the bullet since the bullet receives more impulse from the ex...

Explain this using the impulse-momentum theorem. By the theory of momentum, change in momentum of an object equals the impulse applied to it meaning that the long barrel of the rifle covers a huge amount of motion of the bullet since the bullet receives more impulse from the expanding gases with...

KPE160 DOUG PREP QUESTIONS AND ANSWERS 100% PASS Centre of Gravity vs Centre of Mass - Answer- centre of mass depends on the distribution of mass (not gravitational field) and it doesn't change even if you move or orient yourself differently. Centre of gravity is a unique point which weight is balanced, it can change based on orientation and also takes into account mass distribution. Is it harder to lift or lower a mass? Which feels harder and why? - Answer- It takes the same amount of f...
