Answer:
Weight is best described as:
B.a measure of gravitational force on an object.
Explanation:
- The force with which an object is attracted by any celestial body is called the weight of the body.
- Since, Force = Mass × Acceleration
Weight= Mass × Acceleration due to Gravity(g)
- The gravitational force exerted by a body greatly depends on the mass of the body.
- Greater the mass greater is the weight.
- Gravity of a body with Greater mass will be more therefore the weight of a body varies from place to place and on different celestial bodies.
- For example, The mass of the Earth is six times greater than the moon and thus a body moon weighs one-sixth of its weight on Earth.
Here the mass of the body is a constant quantity and thus the acceleration due to gravity differs.
