LMEC-9 Apparatus of Collision and Projectile Motion
Collision between objects is a common phenomenon in nature. Simple pendulum motion and flat throw motion are the basic contents of kinematics. Energy conservation and momentum conservation are important concepts in mechanics. This collision shooting experimental instrument studies the collision of two spheres, the simple pendulum motion of the ball before collision and the horizontal throwing motion of the billiard ball after collision. It uses the learned laws of mechanics to solve practical problems of shooting, and obtains the energy loss before and after collision from the difference between theoretical calculation and experimental results, so as to improve students’ ability to analyze and solve mechanical problems.
1. Study the collision of two balls, the simple pendulum motion of the ball before collision and the horizontal throwing motion of the billiard ball after collision;
2. Analyze the energy loss before and after collision;
3. Learn the actual shooting problem.
