Questions and Answers
What is the unit of force in terms of fundamental units (kg, m, s)?
What is the unit of force in terms of fundamental units (kg, m, s)?
kg⋅m/s²
Explain how the unit of work is derived from the units of force and distance.
Explain how the unit of work is derived from the units of force and distance.
Work is defined as force multiplied by distance. The unit of force is kg⋅m/s², and the unit of distance is m. Therefore, the unit of work is kg⋅m/s² × m, which simplifies to kg⋅m²/s².
What is the relationship between the units of velocity and acceleration?
What is the relationship between the units of velocity and acceleration?
Acceleration is the rate of change of velocity. Therefore, the unit of acceleration is the unit of velocity divided by time. Since the unit of velocity is m/s and the unit of time is s, the unit of acceleration becomes m/s².

Study Notes
Area
- Area equals length multiplied by breadth
- Unit: m² (meters squared)
Volume
- Volume equals length multiplied by breadth multiplied by height
- Unit: m³ (cubic meters)
Density
- Density equals mass divided by volume
- Unit: kg/m³ (kilograms per cubic meter) or kgm⁻³ (kilograms per cubic meter)
Velocity
- Velocity equals displacement divided by time
- Unit: m/s (meters per second) or ms⁻¹ (meters per second)
Acceleration
- Acceleration equals change in velocity divided by time
- Unit: m/s² (meters per second squared) or ms⁻² (meters per second squared)
Force
- Force equals mass multiplied by acceleration
- Unit: kgm/s² (kilograms multiplied by meters per second squared) or kgms⁻² (kilograms multiplied by meters per second squared)
Work
- Work equals force multiplied by distance
- Unit: kgm²/s² (kilograms multiplied by meters squared per second squared) or kgms⁻² * m (kilograms multiplied by meters squared per second squared multiplied by meters) This value is often written as kgm²/s² or kgm²s⁻²
