Two falling inflated balls of different masses land at the same time. arrowRight A large, massive dog weighs more than a small dog. arrowRight A crumpled ball of paper falls faster than a sheet of paper of the same mass. arrowRight

Answer 1

The force of gravity increases with an increase in the mass of objects. . . . A large, massive dog weighs more than a small dog.

Acceleration due to gravity is independent of the mass of objects. . . . Two falling inflated balls of different masses land at the same time.

Air resistance increases with an increase in the surface area of objects. . . . A crumpled ball of paper falls faster than a sheet of paper of the same mass.

Answer 2

Answer:

1). The force of gravity increases with an increase in the mass of objects

    A large, massive dog weighs more than a small dog.

2). Acceleration due to gravity is independent of the mass of objects

    Two falling inflated balls of different masses land at the same time.

3). Air resistance increases with an increase in the surface area of objects

    A crumpled ball of paper falls faster than a sheet of paper of the same mass.

Explanation:

1). Force of gravity on an object placed near the surface of earth is given by

F = mg

so here if mass of the object is more then it will have more gravitational force due to earth so massive dog weigh more than small dog

2). Acceleration due to gravity is acceleration of an object due to its gravitational force

$a = \frac{F}{m} = g$

so here for all objects near the surface of earth acceleration is due to gravity and remains constant.

So here if two different object will fall from same height under gravity then both will reach ground at same time.

3). Air drag or air resistance depends on area of object so if area of object is more then it will experience more air drag

This will show that if a paper is crumpled then its area will be less and then it will have less resistance while open paper has more area and due to its more resistance it will fall slowly than crumpled paper
