Study Notes
Parallel Forces
- Parallel forces act in the same direction
- Like parallel forces act in the same direction, for example, the weight of multiple apples acting downwards
- Unlike parallel forces act in opposite directions, for example, the weight of an apple pulling it downwards and the tension in a string pulling the apple upwards
Addition of Forces
- Force is a vector quantity with magnitude and direction
- Forces can be added
Resolution of Forces
- The process of splitting a force into its components is called the resolution of forces
- The components are called perpendicular components if they are perpendicular
- The equation for force F is expressed as $F = F_x + F_y$
- The x-component of F can be calculated with $F_x = cos θ \times F$
- The y-component of F can be calculated with $F_y = sin θ \times F$
