Those energies must have originated from somewhere. A stored “explosion” potential energy is converted to kinetic energy and released to the fragments. This potential energy can come from many sources. It can be chemical, nuclear, electrical or as simple as the stored energy in a compressed spring. A real-world explosion will not perfectly convert the stored explosion energy into KE with 100% efficiency. Some will be lost to other forms. Consider an exploding festival ball at a fireworks show. explosion doesn’t only scatter the fragments—it also releases heat, a concussive boom and glowing light.

6-4 APPARATUS Dynamics Track, Photogates mounted on support stands (x2), Dynamics Carts (2x magnetic, 1x nonmagnetic), photogate flags (2x), Steel Weight, Digital Inclinometer (Angle Cube), Triple Beam Balance. PROCEDURE Preparation 1.Connect the photogates to the LabPro interface. Plug the photogates into the “DIG/SONIC 1” and “DIG/SONIC 2” ports.2.Launch LoggerPro and click on the File Open menu, go to the Probes and Sensors\ Photogatesfolder, then open the Collision Timer document. 3.Adjust the two boxes “PhotogateDistance1” and “PhotogateDistance2” to the width of the flags.4.Level the track. Use the digital inclinometer to check the track in the center and at both ends. Also try gently rolling a cart in both directions on the track to ensure it doesn’t prefer to roll in one direction more than the other. 5.Place the two photogates near the center of the track with about 20cm between them. They need to be as close together as possible but still far enough apart that the two photogate flags have room to clear the gate between measurements. Elastic Collisions 6.Arrange the carts on the track such that the “projectile” (m1) is before Photogate 1 (determined by which port you plugged the photogate into on the LabPro), and the target” (m2) is between the two photogates. Both carts should have their magnetic sides facing one another. Plug a flag into each cart on the side facing the opposite cart. 7.Click “Collect” in LoggerPro and wait a moment for the system to begin gathering data. Give Cart 1 a slight push toward Photogate 1. The software will measure the speed of any cart that passes through the photogates. Record to Data Table 1 the speeds of cart 1 and cart 2 before and after the collision as demonstrated in the example in the image. (The image data is for a single cart passing through both gates and is not identical to what you see on the experiment. Pay close attention to the order the carts cross the gates so you know which measurement corresponds to which cart.)
