|
Object X is in a larger gravitational field than object Y and both have the same weight.
|
|
|
Object X shows a greater resistance to change in motion than object Y and both experience the same resultant force.
|
|
|
Object X has a lower density than object Y and both occupy the same volume.
|
|
|
Object X moves at a greater speed than object Y and both possess the same kinetic energy.

Detailed explanation-1: -Mass is the measure of an object’s matter (what it’s made up of). The greater an object’s mass, the greater its gravitational force.
Detailed explanation-2: -According to theory, the reason mass is proportional to gravity is because everything with mass emits tiny particles called gravitons. These gravitons are responsible for gravitational attraction. The more mass, the more gravitons.
Detailed explanation-3: -As the mass of the body increases, the inertia increases. This means that a body with higher mass does not change its velocity easily.
Detailed explanation-4: -We know that weight is equal to the product of mass and gravitational force applied. So, W = MG where w is the weight, M is the mass, and G the gravitational force. Hence, it can also be interpreted as ‘the weight of an object is directly proportional to its mass’.
