Objective: To study the conservation of energy and momentum using projectile motion. Theory: The ballistic pendulum demonstrates both the constant horizontal velocity in projectile motion and the conservation of momentum. Because there is no acceleration in the horizontal direction‚ the horizontal component (v_x) of the projectile’s velocity remains unchanged from its initial value throughout the motion. In a closed isolated system‚ if no net external force acts on a system of particles‚ the total
