Question

Three different weights fall from a certain height under vacuum. They will take

• A. Same time to reach earth
• B. Times proportional to weight to reach earth
• C. Times inversely proportional to weight to reach earth
• D. Unpredictable

Answer 1

Answer:

A. Same time to reach earth

• All objects, regardless of mass, will fall at the same rate. This is mainly due to the force of gravity and the acceleration due to gravity.

• The force of gravity is proportional to the object's mass.

• The force of gravity is greater on the heavier object than on the lighter object.

• This means that an object with twice the mass will be pulled toward the earth, with twice the force.

• On the other hand, the object that is twice the mass of another object will be accelerated twice as slowly as the lighter object, given the same gravitational force.

• The heavy and light objects travel at the same rate because, there are two competing factors that cancel each other out.
