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

compare the change in momentum of the cart with the integral of the measured force vs time graph. Data: Item | Value | Mass of Cart | 516g | Impulse | .35N | Velocity before | .343 m/s | Velocity after | -.318 m/s | Momentum before | .177 kg m/s | Momentum after | -.163 kg m/s | change | -.340 kg m/s | Questions: 1.Why is it desirable to have the same initial speed for each data run? If speed differs‚ the momentum will be effected. As velocity increases‚ momentum increases. 2.How

Introduction to Mechanisms Yi Zhang with Susan Finger Stephannie Behrens Table of Contents 1 Physical Principles This chapter introduces the basic physical principles behind mechanisms as well as basic concepts and principles required for this course. 1.1 Force and Torque 1.1.1 Force Force: an agent or influence that‚ if applied to a free body results chiefly in an acceleration of the body and sometimes in elastic deformation and other effects. Every day we deal with forces

WHAT IS TORQUE? Torque is a measure of how much a force acting on an object causes that object to rotate. The object rotates about an axis‚ which we will call the pivot point‚ and will label ’O ’. We will call the force ’F ’. The distance from the pivot point to the point where the force acts is called the moment arm‚ and is denoted by ’r ’. Note that this distance‚ ’r ’‚ is also a vector‚ and points from the axis of rotation to the point where the force acts. (Refer to Figure 1 for a pictoral

Throwing a football When the football travels through the air for a long pass it always follows a curved path because the force of gravity influences the movement of the ball in the vertical direction. As the ball travels up‚ gravity slows it down until it stops briefly at its peak height; the ball then comes down‚ and gravity accelerates it until it hits the ground. Projectile motion is the path of any object that is launched or thrown and has an arched course (howstuffworks) For the football

is an impulse. This is the force multiplied by the length that this force is applied. Impulse = 10‚000N multiplied by 0.0005s / 0.046kg = 108.69 This would mean that the ball is moving
Premium Classical mechanics Newton's laws of motion Force
An impulse is something that changes an objects momentum‚ and is the product of force and the time which that force acts. Impulse is expressed in the equation Impulse=Ft‚ where F is the force and t is the time on which that force is applied. Impulse is essentially the change in momentum of an object. If we a car with a mass of 1500kgs was driving at a velocity of 20ms-1‚ its momentum would be 30‚000kgms-1. If we assume that this vehicle crashed

this. I am assuming finding velocity is the sole purpose of applying the law of conservation of momentum. Is this true? I also would like to note that a graph could not be drawn in some situations again due to me lacking the technology to send photos of handwritten notes. Hence there is sadly no examples of a problem for translational equilibrium and for the force-time graph in which impulse can be identified. I also have referred to explosions as divisions. Is this appropriate? Newton’s
