This text is adapted from Openstax, University Physics Volume 1, Section 3.5: Free-fall. The projectile motion of an object in 2-dimensional space.A meteoroid accelerating toward the Earth's center.Some real-life examples of free-fall include: However, the velocity of the object dropped first will always be greater than the velocity of the object dropped later. Similarly, if two objects are dropped in succession, then the time required for them to reach the ground will be the same. The acceleration experienced by all objects in free-fall is constant therefore, any two objects dropped from the same height and location on the Earth will fall to the ground at the same speed, provided that the air resistance is neglected. The dynamics of free-fall motion can be calculated using kinematic equations of motion, since free-fall acceleration is constant. Note: when a body falls freely, it is always under the force of gravity and thus experiences acceleration due to gravity. Under rules of physics, the vertical position of the object is affected only by a constant acceleration, and horizontal velocity is also normally constant. Free-fall is experienced not only by objects falling downward, but also by all objects whose motion is influenced by gravitational force alone. For free-falling bodies, the acceleration due to gravity is constant, irrespective of their mass. Rearrange the equation to solve for the position as this is one of the factors that will connect both parts of this problem.

Practically, free falling can only take place in vacuum. High School Physics : Freefall Study concepts, example questions & explanations for High School Physics. An object falling without any air resistance under the influence of gravitational force is said to be in free-fall. Free falling is a motion under force of gravity as the only force acting on the moving object.
