Study Notes
Density
- Density is calculated using the formula ( D = \frac{M}{V} ), where ( D ) is density, ( M ) is mass, and ( V ) is volume.
Speed
- Speed is defined as the distance traveled over the time taken, represented by the formula ( S = \frac{D}{T} ), where ( S ) is speed, ( D ) is distance, and ( T ) is time.
Velocity
- Velocity is speed with a directional component, calculated as ( V = \frac{D}{T} + \text{direction} ).
Acceleration
- Acceleration measures the change in velocity over time, represented as ( A = \frac{\text{final velocity} - \text{initial velocity}}{t} ).
Electricity
- In electrical contexts, voltage ( V ) can be calculated using Ohm's Law, given by ( V = IR ), where ( I ) is current and ( R ) is resistance.
Force
- Force is calculated using the formula ( F = ma ), where ( F ) is force, ( m ) is mass, and ( a ) is acceleration.
Work
- Work done is the product of force and distance, represented by ( W = FD ), where ( W ) is work, ( F ) is force, and ( D ) is distance.
Power
- Power measures the rate of doing work and is calculated using ( P = \frac{W}{T} ), where ( P ) is power, ( W ) is work, and ( T ) is time.
