1.0 ABSTRACT The objective for this experiment is to verify the momentum equation experimentally through the impact of jet against deflectors. There are four deflectors used in this experiment. The four deflectors are plate‚ hemisphere‚ slope and cone. The loading weights to be used are 0.8 N‚ 1.0 N‚ 1.5 N and 2.0 N. In this experiment‚ the time taken for the water level in the volumetric tank to raise from 10 to 20 L is determined by using a stop watch. The flow rate‚ calculated force and the error

Basic Physics Content with Answers 1. In the absence of air resistance‚ a ball of mass m is tossed upward to reach a height of 20 m. At the 10m position‚ half way up‚ the net force on the ball is A. 2mg. B. mg. C. mg/2. D. mg/4. B is correct‚ as a vector diagram would show. Other choices show carelessness or confusion between force and speed‚ and what constant acceleration means. 2. When you drop a ball it accelerates downward at 9.8 m/s2. If you instead throw it downward‚ then its acceleration

scientist—Albert Einstein‚ who found the special relativity and led a new century of quantum mechanics‚ had benefited from communication. During the time that he was miserable about how the atom moves and the accurate measurement of both situation and momentum of an atom‚ a meeting among all these forward physical scientists stimulates his genius. Exchanging of others’ attitudes arise up his suspicious of Newton’s classical mechanics. Then he transformed his point to a new hypothesis—which is now called

gunpowder and projectile in the muzzle‚ or open end. Nowadays firearms are a little more sophisticated. However‚ the physics behind all guns remain the same. Weapons such as cannons‚ shotguns and rifles‚ work on the basic idea of conservation of momentum and the change in energy from potential to kinetic. When the trigger is pulled the hammer hits the firing pin. The firing pin then hits the primer which causes the powder to burn hence producing lots of gases. This causes the volume behind the

Conclusion: Category 1: Momentum was found that after the collision was less than before the collision by 10%. This was not what has been expected‚ so the difference was fairly significant. This happened because of friction‚ when the two pucks collided‚ they have lost a bit of their momentum‚ so the momentum after the collision differed. Kinetic energy differed more than what was expected‚ it was significantly less after the collision‚ the difference before and after the collision was 63.7%‚

Physics 211 Experiment #9 Impulse – Momentum Experiment Discussion Impulse‚ momentum‚ and the impulse-momentum relationship are defined and discussed in the text. The momentum of an object with mass m and velocity [pic] is [pic]. The impulse of a resultant force from time t1 to time t2 is When the force is plotted versus time‚ the impulse is the area under the curve between t1 and t2. [pic] The impulse-momentum relationship states that if an object with mass m is acted on by a force
