Study Notes
Units and Quantities
- The SI unit of force is Newton (N)
- The SI unit of acceleration is meter per second squared (m/s²)
Electrical Circuits
- The relationship between voltage, current, and resistance in an electrical circuit is expressed by Ohm's Law: V = I × R
Forces
- A non-contact force is a force that acts over a distance, without physical contact, such as gravity or magnetism
Scalar and Vector Quantities
- A scalar quantity is a quantity that has only magnitude, but no direction, such as mass or temperature
Motion
- The area under a velocity-time graph represents the displacement of an object
