Celine Pham Hailey Shall Mary Grace Hardin Patrick Gallagher William Schott Lab 6- Conservation of Linear Momentum Purpose: To demonstrate elastic and inelastic collisions, explosions, and how momentum is conserved. Procedure: We are going to be doing experiments with elastic and inelastic collisions to show us how the momentum is conserved. The data values collected was by using LoggerPro and it will measure the speed of any cart that will pass through the photogates. Once everything is collected, we will answer the questions related to the data and apply our knowledge to the application questions and summarize any conclusions that we have drawn from the data. Analysis Data Table 1: Recorded Speeds Elastic Collisions V1(projectile) Before V1(projectile) After V2(target) After M1(projectile) = M2(target) 0.352 m/s 0 m/s 0.343 m/s M1(projectile) < M2(target) 0.358 m/s -0.121 m/s 0.230 m/s M1(projectile) > M2(target) 0.400 m/s 0.120 m/s 0.491 m/s Inelastic Collisions V1(projectile) Before V1(projectile) After V2(target) After M1(projectile) = M2(target) 0.402 m/s 0.196 m/s 0.194 m/s Explosion V1(rearward half) After V2(rearward half) After Each Piece Equal -0.154 m/s 0.141 m/s Wrap-Up V1(projectile) in Gate 1 V2(projectile) in Gate 1 M1(projectile) By Itself 0.441 m/s 0.435 m/s Date Table 2: Recorded Masses Projectile Cart (M1) 0.50530 kg Magnetic Target Cart (M2) 0.50175 kg Added Steel Weight 0.49920 kg
