How the structure reacts to gravity

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.

This quiz covers the definition of force as a push or pull that can change an object's movement or shape, as well as the three factors that force depends on: magnitude, location, and direction. Learn how changing these variables can impact the structure's overall behavior.
