Impulsive Force Model Worksheet 2: Quantitative Conservation of Momentum Name: ______________________________________ 1. Kim holds a 2.0 kg air rifle loosely and fires a bullet of mass 1.0 g. The muzzle velocity of the bullet is 150 m/s. Find the recoil speed of the gun. Momentum conservation equation: Recoil speed =________________ 2. If the girl in the previous question holds the gun tightly against her body‚ the recoil speed is less. Calculate the new recoil speed for the 48 kg girl

INTRODUCTION In hydroelectric power plant‚ turbine been used to generate power from reservoir of water. Turbine been selected by their characteristic curves based on the potential energy available in the water and the amount of power to be generated. Turbine is a type that develops torque by reacting to the pressure or weight of a fluid. The operation of reaction turbine can be describes by the Newton’s third law of motion that is for every action‚ there is an equal and opposite reaction. In this

Purpose: During our lab‚ Galileo’s Water Clock‚ we created our lab to describe the motion of a ball on a plane using the water clock as an alternative method for measuring time. Our main purpose in this lab was to determine if the displacement of the ball is determined by the time or the time squared. Procedure: Once the water clock was set up‚ a ball was let go from the ramp at various distances for three trials each. Once the ball was let go‚ the water clamp was opened and then immediately

Research question: How does the mass of a muffin cup affect the velocity of the muffin cup? Variables: Independent The mass of a muffin cup‚ grams [g]‚ m Dependent The time it takes for the muffin cup to reach the floor‚ seconds [s]‚ t Controlled Air resistance‚ Newton [N]‚ FA Distance of releasing the muffin cup‚ meters [m]‚ d Reaction time‚ seconds [s]‚ t Method for controlling variables: Air resistance will be controlled by having the same shape of the muffin cup for all tests

The purpose of the egg crash is to design‚ build‚ test‚ and evaluate a landing pad to protect an egg from the collision of a hard surface falling from various heights. An individual should be able to describe the collision in terms of changing momentum‚ impulse‚ impact force‚ and impact time. All moving objects have a quantity of motion‚ otherwise known as momentum. Momentum of a moving object can be found by multiplying the mass of the object by the velocity. Because mass is measured in kilograms

Isaac Newton discovered how gravity worked and had evidence. He showed that it was real at the leaning tower of pisa. That was proof and you still insist he goes to jail. There is much more proof than this. He has shown the example and proved it‚ so why is he in jail? He is in jail because you want him to be. He showed the idea of how gravity worked. I will start with how he got his idea and how it worked. Isaac Newton discovered the basic idea of gravity and proved how it worked when he saw

Stress is the human body’s way of reacting to any form of a threat. When your body feels threatened‚ the nervous system responds to this by releasing stress hormones which prepare the body for any sort of emergency situation. Your heart rate increases‚ muscles begin to tighten‚ blood pressure heightens‚ breath quickens‚ and senses sharpen. These physical changes increase your strength and stamina‚ speed your reaction time‚ and enhance your focus. When at an ideal level‚ stress helps you to stay focused

Projectile Motion By Kaneisha Winch Aim: To investigate whether there is a relationship between the horizontal velocity and vertical velocity by using a 7.5 cm baseball in projectile motion. Hypothesis: There is no relationship between the horizontal and vertical velocity. No matter how fast the horizontal velocity‚ the vertical velocity will remain the same. This has no relation to the size or mass of the ball. Materials: • a baseball with a diameter of approx. 7.5 cm • a tape measurer • a surface

In the seventeenth century‚ the Scientific Revolution gave birth to discoveries of new mathematics and sciences. Isaac Newton‚ in particular‚ was one of the many physicist or mathematicians. Born in new England to a prosperous farmer‚ Isaac Newton would later develop principles to develop modern physics with his most famous work‚ Mathematical Principles of Natural Philosophy. Isaac Newton was the son his parents gave birth to. His father soon died three months after his birth‚ thus leaving him with

STEP 1 – SWING FUNDAMENTALS BALL FLIGHT LAWS The five physical laws of ball flight are invariable‚ no matter who swings the club or where or how a club contacts the ball: • Clubhead speed - The speed a club is travelling when it makes solid contact with ball determines how far the ball will go. • Clubhead path - A ball’s starting direction is determined in part by the line along which the clubhead swings as it contacts the ball. • Clubhead face - The direction of a ball is determined in part by
