How do mass and force affect motion? 1. Marissa puts Marble A in the pocket of the slingshot. She pulls the pocket back 12 inches and then releases it. What happens to the marble? Explain why. 2. Marissa then pulls the pocket back 18 inches and launches Marble A in the same direction and at the same angle as before. Will the marble travel farther than before? Explain why or why not. 3. Next, Marissa puts Marble B in the slingshot. She pulls the pocket back 18 inches, keeping the direction and angle the same as before, and releases it. Will Marble B travel farther than Marble A did in the previous launch? Explain why or why not. NEWTON’S SECOND LAW: MASS, FORCE, AND MOTION PART 1: SLINGSHOT EXPERIMENT Marissa has a new slingshot. She wants to figure out which of these two marbles will travel farther. Marble A is a typical marble.Marble B is bigger than Marble A, and it has a greater mass. Newton’s Second Law of Motion states that the speed and the direction of an object’s motion depend on the mass of the object and the sum of all the forces acting upon it. To better understand Newton's Second Law of Motion, Marissa and Kendrick conduct their own experiments. Read about their experiments, and then answer the questions.

Answer 1

1. When Marissa releases Marble A from the slingshot, it will move in the direction and at the angle she launched it. The motion of the marble will be affected by the force applied by Marissa when she released the slingshot. The force will propel the marble forward in the direction it was launched.

2. If Marissa pulls the pocket back 18 inches instead of 12 inches, the force applied to Marble A will be greater. According to Newton's second law, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. With a greater force, Marble A will experience a greater acceleration, leading to a higher velocity and potentially traveling farther than before.

3. When Marissa uses Marble B instead of Marble A, the only difference is the mass of the marble. If Marble B has a greater mass compared to Marble A, it will experience a greater force when Marissa releases the slingshot, assuming the same force is applied. Therefore, Marble B may travel farther than Marble A did in the previous launch because of its greater mass.
