Mark 8m from the starting point with the tape, be sure to have space past the tape for the ball to land.Each group member will take turns with the ball resting on the palm of their abducted arm, be sure not to hold onto the ball. The student with the ball will run full speed towards the 8m mark. When you reach the tape stop abruptly and let the ball fall off of your hand. The observing students should note where the ball hits the ground first. Each student should sketch the path of the ball and create a free body diagram. Use the concept of momentum to explain the path of the lacrosse ball.
