Question

1. 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.

Answer 1

According to Newton's second law of motion, the acceleration due to gravity is the same for all objects, regardless of their mass. This is approximately equal to 9.8 m/s² on Earth.

Step-by-step explanation:

According to Newton's second law of motion, the net force on an object is responsible for its acceleration. In the case of a falling object, the net force is the gravitational force acting on the object. This gravitational force, commonly called weight, can be represented as a vector pointing downwards.

The magnitude of weight, denoted as w, is the same for all objects regardless of their mass. Therefore, the acceleration due to gravity, denoted as g, is also the same for all objects and is approximately equal to 9.8 m/s² on Earth.
