Question

Explain why all objects near Earth’s surface fall with approximately the same
acceleration, despite having different masses and weights. Justify by using the universal
law of gravitation and Newton’s second law.

Answer 1

Answer:

According to Newton's Second Law:

all objects free fall at the same rate regardless of their mass. Because the 9.8 N/kg gravitational field at Earth's surface causes a 9.8 m/s/s acceleration of any object placed there, we often call this ratio the acceleration of gravity.

different masses hit the ground at the same time:

This is because the Earth's acceleration due to gravity (g) has a constant value irrespective of the mass of the bodies. ... Hence ,two objects with different masses hit the ground at the same time if dropped from equal height.
