Free fall class 9 science chapter Gravity
Free fall refers to the motion of an object under the influence of gravity alone, with no other forces acting on it, such as air resistance.
Acceleration Due to Gravity (g): In free fall, the object accelerates at a constant rate due to gravity, denoted by g, which on Earth is approximately 9.8 m/s².
Independent of Mass: All objects, regardless of their mass, experience the same acceleration due to gravity in the absence of air resistance. For example, a feather and a stone would fall at the same rate in a vacuum.
Velocity and Distance: The velocity of an object in free fall increases uniformly, and the distance covered.
