Question

SCIENCE LESSON:

Which of the following statements best describes the relationship between mass and the acceleration of objects in free fall?

A: Objects with less mass are able to avoid air resistance and fall at faster rate.

B: The greater the mass of an object, the greater the acceleration of the object.

C: The greater the mass of an object, the slower the acceleration of the object.

D: All objects fall at the same rate of acceleration regardless of their individual mass.

(Sorry if I spelt something wrong.)

Answer 1

Answer:

D: All objects fall at the same rate of acceleration regardless of their individual mass.

Explanation:

• According to Newton's law of motion the resultant force and the rate of change in linear momentum are directly proportional.
• Mass is inversely proportional to acceleration and directly proportional to the resultant force.
• An object with more mass will have less acceleration while a lighter object will  have greater acceleration.
• During free fall object will fall at the same rate of acceleration regardless of their individual mass.
• Object under free fall are influenced by gravity and air resistance which is negligible and thus they will have an acceleration equivalent to gravitational acceleration.
