Free fall of stones is a phenomenon that occurs when an object, in this case a stone, is falling under the sole influence of gravity. This means that there are no other forces acting on the stone, such as air resistance or friction.
The only force that is acting on a stone in free fall is gravity. This force is constantly pulling the stone towards the center of the Earth, causing it to accelerate towards the ground at a rate of 9.8 meters per second squared.
The speed of a stone in free fall can be calculated using the formula v = gt, where v is the final velocity, g is the acceleration due to gravity (9.8 m/s²), and t is the time the stone has been falling.
No, the mass of the stone does not affect its free fall. All objects, regardless of their mass, will accelerate towards the ground at the same rate due to gravity. This is known as the equivalence principle.
No, a stone will not stop in free fall unless acted upon by an outside force. This is because gravity is constantly pulling the stone towards the ground, causing it to accelerate. However, the stone's velocity may decrease if it encounters air resistance or hits the ground.
