Changes in mass and weight on surface of Moon with respect to Earth
Answer: 1. Mass remains constant but weight decreases.
Explanation: Mass of an object is always remains constant irrespective of surroundings, movement or circumstances. While weight changes with location because the value of the change in ‘Gravitational Force’ at that place.
Mass: Mass is the amount of ‘Matter’ present in an object. It is represented by ‘m’ in science in its unit is ‘kilogram’.
Weight: It is the force experienced by an object due to gravity. Weight is represented by ‘W’.
W = m * g — where g is gravitational constant.
Value of g – gravitational constant varies with location and hence weight of an object changes.
g (on Earth) = 9.81 m/s2
g (on Moon) = 1.6249 m/s2
As the value of g decreases on Moon so weight of object will also be decreased as compared to its weight on Earth.
