LAB WRITE- UP NAME: MANOUCHEKA FIDEL DATE: 9/19/14 TITLE: BACK AND FOURTH MOTION PURPOSE (Introduction): To qualitatively analyze the motion of objects that move back and forth. Then analyze and interpret back and forth motion in kinematics graphs. Use kinematic graphs to catalog objects that exhibit similar motion. PRELIMINARY QUESTIONS: Finding the average velocity Do any of the four objects listed above move in similar ways? If so

The Maximum Height of the bounce of a ping pong ball Introduction This experiment‚is an investigation into the maximum height of the bounce of a ping pong ball when it is first released.This is because of the unpredictability of the bounce not always reaching the same height.This we can assume their are many factors effecting the bounce of the ping pong ball.The following experiment will determine how different surfaces on which a ping pong ball is released affects the height of the first

Part B Now‚ suppose that Zak’s younger cousin‚ Greta‚ sees him sliding and takes off her shoes so that she can slide as well (assume her socks have the same coefficient of kinetic friction as Zak’s). Instead of getting a running start‚ she asks Zak to give her a push. So‚ Zak pushes her with a force of 125 \rm N over a distance of 1.00 \rm m. If her mass is 20.0 \rm kg‚ what distance d_2 does she slide after Zak’s push ends? Remember that the frictional force acts on Greta during Zak’s push and

Collisions Inelastic Collisions Elastic Collisions Stationary Target Moving Target Collisions in 2-Dimensions (Glancing Collisions) Inelastic Collisions Collisions in which kinetic energy is not conserved. Initial kinetic energy is transformed into other types of energy (thermal‚ potential etc.) Total final kinetic energy is less than the total initial kinetic energy. If two objects stick together as a result of the collision‚ the collisions is inelastic. Even though the

Example problems involving collisions 1) On a horizontal frictionless surface a puck of mass m initially at speed u collides head-on (without rotation) with a stationary puck of mass M. Find the velocities of both puck after the collision if: i) the collision is fully elastic ii) the collision if fully inelastic. i) momentum: kinetic energy: mu = mv+MV (+ve in direction of initial u) 1 /2 m u2 = 1/2 m v2 + 1/2 M V2 2 eqns in 2 unknowns: V = (u - v) m/M substitute in K eqn: u2 = v2 + (M/m) V2 =

Balloon powered car 1 How does the balloon car demonstrate that energy is transformed from potential energy to kinetic energy? Explain When the balloon has air inside it‚ the car and the balloon have potential energy stored inside it. When the air is released the car moves forward and has kinetic energy. 2 Where is most of the energy ’lost’ in this car? There is a number of different possible reasons that energy could have been lost in our car: some of the air in the balloon may have escaped through

The roller coaster is so fast. It is a roller coaster that is never seen before. When you see some roller coaster have some loops and small turns‚ well this is the complete opposite. Consequently‚ You will experience so much during the ride and what is even better is if you chose to ride in a cart that will go twice around for a little bit more so you do not have to wait in line again to ride it another time. The carts are aerodynamic so that he has less air resistance they will have a higher speed

Abstract: In this experiment‚ two object collided both elastically and in inelastically‚ the purpose of this experiment is to study the principle of conservation of momentum in collisions using two bodies. We also calculated the amount of kinetic energy in elastic and inelastic collisions before and after the collision. Introduction: When bodies collide with each other‚ the total momentum p = mv‚ is always conserved regardless of the type of collision provided no external forces are present. There
