Understanding Free Fall
Free fall refers to the motion of an object when it is only under the influence of gravitational force, without any other forces acting on it, such as air resistance. This concept is crucial in physics and helps to explain a variety of natural phenomena. Key principles include:
- Acceleration due to Gravity: All objects in free fall experience the same acceleration, approximately 9.81 m/s² on Earth, regardless of their mass.
- Velocity and Displacement: The velocity of a freely falling object increases as it falls, and its displacement can be calculated using kinematic equations.
- Time of Fall: The time an object takes to fall can be calculated based on its initial height and the acceleration due to gravity.
