Which requires more force to accelerate an object?

A. An object that weighs 9.90 kg
B. An object that weighs 99 kg
C. Both A and B
D. None of the above

Answer :

Final answer:

An object that weighs 99 kg requires more force to accelerate it compared to an object that weighs only 9.9 kg. This is based on Newton's Second Law of Motion (F=ma) and the equation for weight (w=mg), indicating that more mass requires a greater force.

Explanation:

The subject of this question deals with the concept of force, mass, and acceleration stemming from the foundational principles of Physics. The force required to accelerate an object is contingent on its mass, as dictated by Newton's Second Law of Motion, which states that the force required to move an object is equal to its mass times the acceleration (F=ma). Hence, an object with a higher mass requires a larger force to be moved.

To answer your question: B. An object that weighs 99 kg requires more force to accelerate it, compared to an object that weighs 9.9 kg. The relationship between mass and force can also be seen in the equation for weight (w=mg), where m represents mass and g is the acceleration due to gravity (approximately 9.80 m/s² on Earth). Therefore, an object that is heavier (higher in mass) naturally requires a greater force to move it due to its weight.
