Lab 5 Conservation of Momentum and Energy Abstract The physics laws governing conservation of momentum and mechanical energy were investigated by performing multiple experiments with differing conditions. Conservation laws state energy is to be conserved in systems with no net external forces. Two trials consisted of inelastic collisions and two trials consisted of elastic conditions. Photogate software helped decipher initial and final velocities in order

INTRODUCTION During collisions involving two bodies‚ equal and opposite forces are set up between them. These impact forces influence the subsequent motion of the bodies. Momentum of the system (consisting of both bodies) is preserved if both bodies are free to move in space. This is because there is no external forces act on the system. The forces acting between the bodies during the small interval of time when they are in contact cause changes in the velocities of each separate body. An

Angular momentum and its properties were devised over time by many of the great minds in physics. Newton and Kepler were probably the two biggest factors in the evolution of angular momentum. Angular momentum is the force which a moving body‚ following a curved path‚ has because of its mass and motion. Angular momentum is possessed by rotating objects. Understanding torque is the first step to understanding angular momentum.<br><br>Torque is the angular "version" of force. The units for torque are

Experiment 4 Inelastic Collisions‚ Conservation of Momentum and Non Conservation of Kinetic Energy Preparation Prepare for this week’s experiment by studying Newton’s Laws‚ linear momentum‚ and kinetic energy. Principles In this experiment you will study a collision where a moving object strikes and sticks to an initially motionless object. When the colliding objects stick together the collision is said to be completely inelastic. The net momentum of the system should not change‚ but the net kinetic

the final momentum resulting in an unusable attempt. 3. Discuss any differences in total momentum before and after the collision There were small amounts of differences in momentum before and after the collision‚ this can be related back to random and systematic errors throughout the experiment such as the equipment being slightly off. There is also energy lot through the form of sound and friction of the wheels. Introduction: This experiment explores the conservation of momentum and energy

CONSERVATION OF MOMENTUM PRACTICAL WRITE UP AIM: To investigate if momentum is conserved in two-dimensional interactions within an isolated system. HYPOTHESIS: Without the effects of friction the momentum will be conserved in the isolated system. In all three experiments the momentum before the interaction will equal the momentum after the interaction. METHOD: An air hockey table was set up and a video camera on a tripod was placed over the air hockey table. The camera was positioned so it was
