4. You might have heard of Galileo's famous experiment to demonstrate that all objects, regardless of their weight and assuming no air resistance, fall at the same acceleration (Figure 5). Use Newton's Second Law of Motion to show that for all objects, regardless of their mass, the acceleration due to gravity will be g, which we approximate as 9.8 m/s².
