Study Notes
Force
- Force is a push or pull that tends to cause an object to change its movement or shape.
- There are three variables that affect force: magnitude, location, and direction.
- Magnitude: the size of the force, which affects the overall movement of the structure.
- Location: where the force is being applied, which affects how the structure reacts to the force.
- Direction: the direction in which the force is being applied, which can work with or against gravity.
Unit of Force
- The unit of force is the newton (N).
Mass
- Mass is the amount of matter in an object, which remains constant regardless of location.
- Weight is affected by gravity and changes with location, but mass remains the same.
- The unit of mass is the kilogram (kg).
Similarities and Differences between Mass and Force
- Mass is a measure of the amount of material in an object, while force is a push or pull that causes an object to change its movement or shape.
- Mass is measured in kilograms (kg), while force is measured in newtons (N).
- Weight is a force that is affected by gravity, whereas mass is a constant property of an object.
