    Study Notes

    Force

    • A force is defined as a push or pull exerted by one object on another during their interaction.
    • It can change an object's state of motion; thus, it is a vector quantity with both magnitude and direction.

    Types of Forces

    • Applied Force (F_app): The force exerted on an object by a person or another object.
    • Tension Force (F_tens): The force transmitted through strings or cables when they are pulled tightly from opposite ends.
    • Normal Force (F_norm): The supportive force exerted by a stable surface on an object in contact with it.
    • Friction Force (F_frict): A force opposing the motion of an object, acting in the opposite direction of movement.
    • Elastic Force (F_e): The force exerted by an object that is stretched or compressed.
    • Gravity Force (Weight) (F_grav): The gravitational attraction between an object and the Earth or another massive body.
    • Air Resistance Force (F_air): A frictional force that opposes the motion of objects traveling through the air.

    Magnitude of Force

    • Refers to the strength of the force, usually measured in Newtons (N).

    Effects of a Force

    • Can initiate motion in a stationary object or stop a moving object.
    • Alters the speed of a moving object.
    • Changes the direction of a moving object's path.

    Balanced Forces

    • Consist of equal forces acting in opposite directions.
    • Do not alter an object's state of rest or motion, resulting in no movement.

    Unbalanced Forces (Net Force)

    • The sum of all acting forces that result in a change in motion.
    • Can set an object into motion or stop its movement.

    Combining Forces

    • Forces directed North, East, Up, or Right are positive (+).
    • Forces directed South, West, Down, or Left are negative (-).
    • For forces acting in the same direction, add their magnitudes and maintain the common direction.
    • For forces acting in opposite directions, subtract the smaller magnitude from the larger one and use the direction of the larger force.
