Free Fall: Newton’s Second Laws of Motion

Newton’s second law provides an explanation for the equal accelerations of freely falling objects of various masses. Acceleration is equal when air resistance is negligible. Acceleration depends on force (weight) and inertia. This lecture broedly focus on Free Fall, in terms of Newton’s Second Laws of Motion. The greater the mass of the object is the greater its force of attraction toward the Earth. The smaller its tendency to move i.e., the greater its inertia. So, the acceleration is the same. It is equal to the acceleration due to gravity: 10 m/s² (precisely 9.8 m/s²).
