![]() ![]() Now, we can calculate the final velocity (v) using the formula: Using the free fall formula to calculate the distance fallen: d = (1/2)x g x t² What is its final velocity?Īcceleration due to gravity (g) = 9.8 m/s². Therefore, the stone falls approximately 44.1 meters in 3 seconds.Įxample 2: An object is released from rest and falls freely for 2 seconds. Substituting the given values: d = (1/2) x 9.8 x (3)² Using the free fall formula: d = (1/2) x g x t² Understanding the free fall formula allows us to analyze and predict the motion of objects in the absence of other forces, providing valuable insights into various physical phenomena and practical applications.Įxample 1: A stone is dropped from a tall building. It helps determine the vertical motion of objects in scenarios such as objects falling from a height, projectiles launched vertically, or bodies dropped into a well. The free fall formula is often used to calculate the distance fallen or the time of fall for objects dropped or thrown vertically. It neglects factors such as air resistance, the rotation of the Earth, and the variation of gravity with altitude.Ĭonsistent units need to be applied when applying the formula and consider the direction of motion (positive or negative) based on the chosen reference frame. The formula for free fall assumes that the object starts from rest (initial velocity u = 0) and is only influenced by the gravitational force. Time (t): It refers to the duration of the free fall, measured in seconds (s).The unit of acceleration is meters per second squared (m/s²). Acceleration due to Gravity (g): It is the constant acceleration experienced by objects in free fall due to the gravitational force.The unit of distance can be meters (m) or any other suitable unit of length. Distance (d): It represents the vertical distance traveled by the falling object.To calculate the final velocity (v) at the end of free fall: v = gt.To calculate the time of fall (t): t = √(2d/g).The formula can be rearranged to solve for other quantities. Where: d represents the distance or height fallen, g is the acceleration due to gravity, and t is the time of fall. The formula for calculating the distance (d) traveled by an object in free fall is given by: ![]() This acceleration acts downwards, towards the center of the Earth. In free fall, all objects experience the same acceleration due to gravity (g), which is approximately 9.8 m/s² near the surface of the Earth. Free fall refers to the motion of an object under the sole influence of gravity, without any other forces acting on it. ![]()
