In classical mechanics, free fall is any motion of a body where gravity is the only force acting upon it. A freely falling object may not necessarily be falling down in the vertical direction.

2025年3月8日 · freefall, in mechanics, state of a body that moves freely in any manner in the presence of gravity. The planets, for example, are in free fall in the gravitational field of the Sun. An astronaut orbiting Earth in a spacecraft experiences a condition of weightlessness because both the spacecraft and the astronaut are in free fall.

2025年3月16日 · For the ideal situations of these first few chapters, an object falling without air resistance or friction is defined to be in free fall. The force of gravity causes objects to fall toward the center of Earth.

Any object that is being acted upon only by the force of gravity is said to be in a state of free fall. There are two important motion characteristics that are true of free-falling objects: Free-falling objects do not encounter air resistance.

2023年2月16日 · Free fall and projectile motion describe objects that are moving through the air and acted on only by gravity. In this post, we will describe this type of motion using both graphs and kinematic equations.

Free fall is the movement of an object or body only under the influence of gravity. The acceleration is caused by this external force on the object, hence the motion of the object will be accelerated. Thus, free-fall motion is also popularly known as acceleration due to gravity.

This free fall calculator is a tool for finding the velocity of a falling object along with the distance it travels. Thanks to this tool, you can apply the free fall equation for any object, be it an apple you drop or a person skydiving.

Free fall occurs whenever an object is acted upon by gravity alone. Try this experiment. Obtain a piece of paper and a pencil. Hold them at the same height above a level surface and drop them simultaneously.

There are a few conceptual characteristics of free fall motion that will be of value when using the equations to analyze free fall motion. These concepts are described as follows: An object in free fall experiences an acceleration of -9.8 m/s/s.

2019年1月14日 · Free fall is the motion of a body where its weight is the only force acting on an object. Free Fall: This clip shows an object in free fall. Galileo also observed this phenomena and realized that it disagreed with the Aristotle principle that heavier items fall more quickly.
