- Dimensional analysis relates physical quantities to their dimensions.
- Mass density is defined as mass per unit volume, represented as [ML⁻³ T⁰].
- Power is defined as work done per unit time, expressed as [M¹ L² T⁻³].
- Acceleration measures the change in velocity over time with a dimensional formula of [M⁰ L¹ T⁻²].
- Impulsive forces are characterized by impulse, defined as force multiplied by time, leading to [M¹ L¹ T⁻¹].
- Pressure, defined as force per unit area, corresponds to the dimensions [M¹ L⁻¹ T⁻²].
- The coefficient of viscosity involves force, area, and velocity gradient, represented as [M¹ L⁻¹ T⁻¹].
- Energy or work is quantified as force times distance, yielding the dimensional representation of [M¹ L² T⁻²].
- Frequency is the reciprocal of the time period, leading to the formula [M⁰ L⁰ T⁻¹].Here are the study notes for the provided text:
