Write a theory and hypothesis. Define the concept and then state how you would measure the concept. Can you show me an example of one so I know what to look for when taking my test. Thank You

Theory: The theory of gravity states that any two objects in the universe exert a force of attraction on each other, known as gravity. This force is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

Hypothesis: "Increasing the mass of an object will increase the force of gravity between it and another object of fixed mass."

Concept: The concept here is the force of gravity between two objects, which is determined by their masses and the distance between them. This concept is central to understanding how gravity works in the universe.

Measurement: To measure the force of gravity between two objects, you can use a simple and commonly known experiment involving a spring scale. First, measure the mass of one object (e.g., a metal ball) using a balance. Then, attach the second object of fixed mass (e.g., another metal ball) to the spring scale and measure the force required to keep them separated at a fixed distance (e.g., 10 cm). Repeat the experiment several times, increasing the mass of the second object each time, and record the corresponding forces measured by the spring scale. By analyzing the data, you can determine the relationship between mass and the force of gravity.

Example: Let's say you are taking a physics test that includes a question related to exploring the hypothesis mentioned above. The test may provide you with a scenario involving two objects and their masses, and ask you to calculate the force of gravity between them. You would need to use the equation for gravitational force (F = G * (m1 * m2) / r^2) and plug in the given masses (m1 and m2) and the distance (r) between them. By performing the necessary calculations, you can determine the force of gravity.
