Forces and Free-body Diagrams: Learn how to navigate a drone

I.

OBJECTIVES Describe the overall objective and make a hypothesis

-

-

II.

The overall objective of the laboratory simulation is to learn about the basic laws of motion by Isaac Newton and its application on free-body diagrams. The student is expected to learn to recognize certain real-world problems and to recognize the forces within a problem through free-body diagrams. The hypothesis of this laboratory simulation is that the student can learn and utilize Newton’s laws and free-body diagrams and learn to recognize forces based on individual problems.

BACKGROUND OF THE TOPIC Introduce relevant background knowledge on this topic

-

III.

The topic of forces and free-body diagrams has been taught to the student previously. Forces are interactions that causes change. Based on Newton’s 2nd law F=ma, force is directly proportional to acceleration, and force is inversely proportional to mass. Free-body diagrams are composed of vectors which represent the forces of a certain problem. It will help on determining the direction of the resultant force.

SUMMARY OF PROCEDURE Summarize the steps taken in the simulation

-

IV.

The student is first introduced to Sir Isaac Newton who discovered the laws of motion. The concept of Forces, Magnitude, and Net Forces are introduced through vector diagrams. Then, the concept of center of gravity is introduced which is based on the geometry of a certain object. Dr. One then introduced three situations which has varying types of forces on each situation (spring, underwater, wedge). Lastly, Dr. One introduced free-body diagrams and introduced problems involving it which concludes the simulation.

RESULTS Explain the obtained results

-

Forces, magnitude and net force are three terms that are related to each other. Forces are the interactions that causes change, magnitude is the quantity of force, while the net force is the sum total of forces in a system. It is also demonstrated in the simulation that the center of gravity of a symmetrical object is always on its center point, and the center of gravity varies with the geometry of an object. On the three introduced situations (spring, underwater, ledge), there are different types of forces acting in different situations. For the spring, there is weight and restoring force; underwater, weight and buoyancy; wedge, weight, friction

force and normal force. The free-body diagrams are solved just like how vector diagrams are solved....
