  • Equilibrium
    A state where all forces acting on an object cancel out, resulting in zero net force.
  • Free Body Diagram
    A visual representation of all forces acting on an object, used to analyze equilibrium.
  • Tension Force
    The pulling force transmitted through a string, cable, or rope when it is pulled tight.
  • Weight Force
    The force due to gravity acting on an object's mass, directed downwards.
  • Trigonometric Functions
    Mathematical functions like sine and cosine used to decompose forces into components.
  • Components
    The parts of a force acting along the x and y axes, derived using trigonometry.
  • Cosine
    A trigonometric function used to find the adjacent side of a right triangle.
  • Sine
    A trigonometric function used to find the opposite side of a right triangle.
  • Net Force
    The overall force acting on an object, calculated as the vector sum of all forces.
  • Newton
    The SI unit of force, symbolized as N, representing the force needed to accelerate 1 kg by 1 m/s².
  • Magnitude
    The size or length of a vector, representing the amount of force without direction.
  • Angle
    The measure of rotation needed to bring one line or plane into coincidence with another.
  • Axis
    A reference line used in a coordinate system to determine the position of points.
  • Decomposition
    The process of breaking a force into its x and y components using trigonometry.
  • Diagram
    A simplified drawing showing the appearance, structure, or workings of something.
