The glider, which will be in motion, will have a larger mass than the stationary one in part b, the intention is to test the conservation of momentum and of kinetic energy for a perfectly inelastic collision between a moving glider, which runs along a straight line on an air track, and a stationary glider. Phy191 experiment 5: elastic and inelastic collisions 8/12/2014 page 3 in this experiment you will be dealing with a) a completely inelastic collision in which all kinetic energy relative to the center of mass of the system is lost, but momentum is still conserved, and. 10 collisions • use conservation of momentum and energy and the center of mass to understand collisions between two objects • during a collision, two or more objects exert in an elastic collision, the kinetic energy of the system is conserved during the collision.
Linear momentum and kinetic energy introduction the object of this experiment is to investigate the conservation of linear momentum and the conservation of kinetic energy in elastic collisions we will study collisions between two air track gliders one glider is stationary and the other collides with the stationary glider (one glider is heavy. Momentum is dependent on two factors velocity and mass this can be modeled through the equation p=mv where p is the symbol for quantity of momentum, m represents the mass, and v is the velocity. The first glider loses all of its kinetic energy during the collision as the second glider is set in motion with the same original speed as the first glider since the first glider lost all of its kinetic energy, this is a perfectly inelastic collision.
Momentum is a vector quantity and you should properly take the direction into account in your calculations 2 calculate the percent difference between the total momenta before and after the collision %diff = jp f pij p f + pi 2 100 (3) 3 for each case, calculate the kinetic energy of each glider and the total kinetic energy before and after the collision 4. Transcript of air track experiment-introduction collisions between objects are governed by the laws of momentum and energy momentum can be defined as mass in motion the mass, and v is the velocity inelastic collisions converts kinetic energy into other forms of energy therefore, kinetic energy is not conserved purpose materials and. 1 objective the objective of the third experiment of the ph1004 laboratory course is broken down into two parts in part a, the aim is to assess the conservation of momentum and of kinetic energy for an elastic collision between a moving glider, which runs along a straight line on an air track, and a stationary glider. Final momentum of an initially stationary glider, struck by another glider which is initially moving you’ll do this experiment for two different types of collisions, elastic and inelastic elastic collisions are ones where kinetic energy is conserved (the objects bounce off each other without losing any energy. To develop a fundamental understanding of the principle of linear momentum conservation, this experiment makes use of two gliders colliding along a frictionless air track instead, all of the input kinetic energy equals all of the output kinetic energy between the two gliders in the first trial, you will examine an elastic collision.
Write expressions for the total momentum and the total kinetic energy of the two objects now suppose an object of mass m 1 is moving to the right with velocity v 1 and another object of mass m 2 is moving left with velocity v 2 write expressions for the total momentum and the total kinetic energy of the two objects. Physics 2010 conservation of momentum and energy experiment 3 in one dimension (1d), the momentum p of an object of mass m and velocity v is in 1d, we represent the direction of travel by the sign of v and p. Launch the glider at the end toward the center, so that when it collides with the stationary glider the velcro will attach them measure the velocity of the glider before the collision and the two joined gliders after.
Conserationv of momentum in collisions an initial velocity toward the stationary glider collision ii: start both gliders at one end of the track give the rst glider a slow velocity results indicate that momentum and kinetic energy are conserved for elastic collision. Now, make sure that the velcro ends of each glider are facing each other launch the big glider and observe make sure your incident glider goes into gate #1 for this experiment, you will only record two time intervals: the big glider in gate #1 before the collision, and the small glider in gate #2 after the collision.
Physics 2010 conservation of momentum and energy experiment 3 practice pushing glider 1 gently so that it collides and sticks to an initially stationary glider 2 note that the final velocity is much smaller than the initial velocity write expressions for the total momentum and the total kinetic energy of the two objects.
