  1. 3. is a quantity that indicates the mass per unit volume of a substance. It is often expressed in kilograms per cubic meter (kg/m³) or grams per cubic centimeter (g/cm³).
  2. 4. represents a push or pull on an object. It has both magnitude (measured in Newtons) and direction (ex: 10 N to the right).
  3. 8. represents the rotational force applied to an object. It has both magnitude (measured in Newton-meters or Nm) and direction (along the axis of rotation
  4. 9. the degree of hotness or coldness of an object. It is measured in degrees Celsius (°C) or degrees Fahrenheit (°F).
  5. 13. represents the change in position of an object in a particular direction. It has both magnitude (distance) and direction (ex: 10 meters north).
  6. 14. measures the ability to do work or produce heat. Units include joules (J), calories (cal), or kilowatt-hours (kWh).
  7. 15. measures the amount of space occupied by an object. It is usually measured in cubic meters (m³) or liters (L).
  8. 17. is the rate of change of velocity with respect to time. Like velocity, it is also a vector, having both magnitude (e.g., 5 meters per second squared) and direction (ex: westward).

  1. 1. is the product of an object's mass and its velocity. It is a vector quantity because it retains the direction of the velocity.
  2. 2. represents the gravitational force acting on an object. It has both magnitude (measured in Newtons) and direction (toward the center of the Earth).
  3. 3. represents the "how much ground an object has covered" and is measured in units such as meters, kilometers, or miles. It doesn't specify direction.
  4. 5. is the magnitude of velocity. It indicates how fast an object is moving, such as 60 miles per hour or 100 kilometers per hour. It doesn't include direction.
  5. 6. represents the extent of a two-dimensional surface, such as square meters (m²) or square feet (ft²).
  6. 7. measures the force applied per unit area. It is expressed in units like pascals (Pa) or atmospheres (atm).
  7. 10. is the rate at which energy is transferred or converted. It is measured in watts (W), horsepower (hp), or other power units.
  8. 11. measures the duration of an event or the interval between two events. It is measured in seconds, minutes, hours, etc.
  9. 12. is the rate of change of displacement with respect to time. It is a vector that includes both speed (magnitude) and direction (ex: 20 meters per second east).
  10. 16. represents the amount of matter in an object. It is usually measured in kilograms, grams, or other mass units.
