Define the following terms volume, density, relative density, kinetic friction, length?

- Volume: The amount of space occupied by an object or substance, typically measured in cubic units.

- Density: The mass of a substance per unit volume, often expressed in grams per cubic centimeter or kilograms per cubic meter.

- Relative density: The ratio of the density of a substance to the density of a reference substance, often water.

- Kinetic friction: The force that resists the motion of an object when it is in contact with another object and moving relative to it.

- Length: The measurement of the extent of something along its greatest dimension, typically measured in units such as meters, centimeters, or inches.

Volume

- The amount of three-dimensional space occupied by an object or substance.
- Typically measured in cubic units (e.g., cubic meters, cubic centimeters).

Density

- The mass of a substance per unit volume.
- Often measured in kilograms per cubic meter (kg/m³).
- Indicates how tightly packed the particles of a substance are.

Relative Density

- The ratio of the density of a substance to the density of water at 4°C.
- Dimensionless quantity.
- Also known as specific gravity.

Kinetic Friction

- The frictional force that opposes the motion of an object when in contact with another object.
- Depends on the roughness of the surfaces in contact and the force pressing them together.

Length

- The distance between two points.
- Typically measured in linear units (e.g., meters, centimeters, inches).
- Measures the extent of an object or space in one direction.
