Study Notes
Force
- A force is an influence that changes an object's velocity if not balanced by other forces.
- Force is a vector quantity, meaning both magnitude and direction are crucial.
- The SI unit for force is the newton (N).
- Force is represented by the symbol F.
- Force is central to Newton's laws of motion.
Types of Forces
- Common forces in classical mechanics include elastic, frictional, contact (normal), and gravitational forces.
- Torque is the rotational equivalent of force.
- Forces within an object (internal forces) can cause stresses.
- Internal stresses cause no acceleration in equilibrium.
- Imbalances in internal stresses can cause deformation in solids or flow in fluids.
