Question

What would happen to an object if the force of gravity on Earth was decreased by half?

a) Its mass would decrease
b) Its weight would decrease
c) Its density would decrease
d) Its volume would decrease

Answer 1

If the force of gravity on Earth was halved, an object’s weight would decrease, while its mass, density, and volume would remain unchanged.

Step-by-step explanation:

If the force of gravity on Earth was decreased by half, an object's weight would decrease. This occurs because weight is the force of gravity acting on an object's mass. The object's mass would remain the same, as mass is a measure of the amount of matter in an object and does not depend on gravity. Similarly, its density and volume would not change, as these are intrinsic properties of the material and not related to the gravitational force.

It's important to understand that gravitational force is directly proportional to mass and inversely proportional to the square of the distance between two objects. If Earth's gravity is reduced by half, the gravitational force exerted on objects at the surface would be halved, leading to a decrease in weight by half as well.
