Questions & Step-by-Step Solutions
If the mass of the Earth were to double, what would happen to the weight of an object on its surface?
Step 1: Understand that weight is the force of gravity acting on an object.
Step 2: Know that weight depends on two things: the mass of the object and the mass of the Earth.
Step 3: Remember the formula for weight: Weight = Mass of object × Gravitational acceleration.
Step 4: Recognize that gravitational acceleration is affected by the mass of the Earth.
Step 5: If the mass of the Earth doubles, the gravitational force (and thus the gravitational acceleration) also doubles.
Step 6: Since weight is directly proportional to gravitational force, if the Earth's mass doubles, the weight of the object on its surface will also double.
Weight and Mass Relationship – Weight is the force exerted by gravity on an object, which is directly proportional to the mass of the object and the mass of the planet it is on.
