Study Notes
Learning Competencies
- Understand the relationship between force, mass, and motion.
- Recognize that when one object exerts a force on another, an equal and opposite force occurs.
- Apply laws of motion to uniform circular motion.
- Acknowledge that circular motion requires a constant force directed towards the center.
Understanding Forces
- Forces can initiate motion, stop motion, or change the direction of an object.
- Key properties of forces include:
- Magnitude: Strength expressed in Newtons (N).
- Direction: The path in which the force acts.
- Point of Application: The specific location where the force is applied.
- Line of Action: The trajectory that extends through the point of application and parallels the direction of the force.
Force Diagrams
- Free Body Diagrams (FBD) illustrate all forces acting on an object, indicating their magnitudes, directions, and the object's motion.
Balanced Forces
- Balanced forces possess equal magnitude but act in opposite directions (e.g., 15 N forces).
- Objects under balanced forces either remain at rest or maintain a constant speed.
Unbalanced Forces
- Unbalanced forces result in a change in the motion of an object.
- Example: If a box moves to the right, it is acted upon by unbalanced forces.
- Factors in unbalanced forces:
- Friction: Can act against the direction of motion.
- Pushing Force: Example shows a 200 N pushing force against a 100 N friction force.
- Net or Resultant Force is calculated by summing all forces acting on an object:
- When forces act in the same direction, they are added.
- When forces act in opposite directions, they are subtracted.
Mini Task Concepts
- Differentiate between balanced and unbalanced forces through practical examples to understand their effects on motion.
