In this interactive activity adapted from Wake Forest University, learn about the principle of conservation of momentum. Two carts colliding on an air track demonstrate how momentum is conserved in a closed system. Observe six different scenarios—a moving cart colliding with a stationary cart of lesser, equal, or greater mass in both elastic and inelastic collisions—to see how the motion of the carts changes after each collision.
