Study Notes
Types of Forces
- A force that causes an object to start or stop moving is an external force.
- A force that changes the shape of objects is a compressive or tensile force.
Force and Motion
- A force that changes the direction of an object's motion is an external force.
Units of Force
- The SI unit of force is the Newton (N).
Representing Force
- Force is represented by the symbol F.
Rotational Force
- The rotational version of force is called torque.
Deforming Forces
- Forces that are responsible for changes in the shape of an object are deforming forces.
Equilibrium
- In equilibrium, internal mechanical stresses cause no deformation in a body.
