Study Notes
Newton's Laws of Motion
- First Law (Law of Inertia): Objects maintain their state of rest or motion unless influenced by an external force.
- Second Law: Acceleration (a) of an object correlates with net force (F) and inversely relates to mass (m), expressed as F = ma.
- Third Law: Every action has an equal and opposite reaction, emphasizing interaction between forces.
Law of Universal Gravitation
- Every mass attracts all other masses.
- The attractive force is proportional to the product of their masses and inversely proportional to the square of the distance separating them.
Ohm's Law
- The current (I) through a conductor is directly proportional to the voltage (V) across it, given constant temperature.
- Expressed mathematically as V = IR, linking voltage, current, and resistance (R).
Archimedes' Principle
- An object submerged in a fluid experiences an upward buoyant force.
- This buoyant force equals the weight of the fluid displaced by the object.
Bernoulli's Principle
- In a moving fluid, an increase in the fluid's speed results in a decrease in pressure within the fluid.
- This principle explains various phenomena in fluid dynamics and aerodynamics.
Boyle's Law
- For a constant temperature, the volume (V) of a given mass of gas is inversely related to its pressure (P).
- Mathematically stated as PV = k, where k is a constant for the given amount of gas.
