The purpose of this laboratory activity is to measure the acceleration of a falling object assuming that the only force acting on the object is the gravitational force.

**What is the objective of free fall experiment?**

To determine gravitational acceleration by studying the velocity of a falling object as a function of time. A secondary objective is to evaluate the precision of your ruler-fit function, and to compare it to the “best-fit” function as determined by the Graphical Analysis program in the computer.

### What happens to a body falling freely?

In Newtonian physics, free fall is any motion of a body where gravity is the only force acting upon it. In the context of general relativity, where gravitation is reduced to a space-time curvature, a body in free fall has no force acting on it.

**What is the free fall experiment?**

The “modern” study of objects in free fall near the Earth’s surface was begun by Galileo some 400 years ago. In this experiment you will use the free fall of an object to determine the acceleration due to gravity g. The air resistance exerts an upward force, which causes an upward acceleration on the object.

#### What are the 3 cases of free fall?

Examples of Free Fall Motion

- An Object Exhibiting Projectile Motion.
- Fruit Falling from the Tree.
- Stone Dropped from a Hill.
- A Spacecraft in Continuous Orbit.
- Meteors Falling towards Earth.
- Sky Diving.
- Bungee Jumping.
- Shells Falling after Firing.

**How do you prove free fall?**

The best way to see the basic features of motion involving gravity is to start by considering straight up and down motion with no air resistance or friction. This means that if the object is dropped, we know the initial velocity is zero. Once the object is in motion, the object is in free-fall.

## What exactly is meant by a freely falling object?

What exactly is meant by a “freely falling” object? An object in free fall falls under gravity alone with no friction. The acceleration of free fall is about 10 m/s2.

**What is the formula for free fall?**

The formula for free fall: Imagine an object body is falling freely for time t seconds, with final velocity v, from a height h, due to gravity g. It will follow the following equations of motion as: h= \frac{1}{2}gt^2. v²= 2gh.

### What is the law of falling bodies?

The law states that the distances traveled are proportional to the squares of the elapsed times. In other words, in equal successive periods of time, the distances traveled by a free-falling body are proportional to the succession of odd numbers (1, 3, 5, 7, etc.).

**What is the first law of falling bodies?**

His first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia. Since there is no initial air resistance, the object begins to free fall and accelerate.

#### What is the objective of motion in free fall lab?

Motion in Free Fall Lab Report objective: the motion of body falling freely under gravitational attraction will be examined, and from the measured rate at which Sign inRegister Sign inRegister Institutions Southern New Hampshire University Grand Canyon University University of the People Nova Southeastern University University of Wisconsin-Madison

**What happens when a body is allowed to fall?**

If the force is constant magnitude, then the acceleration of the body will also be constant. A body, which is allowed to fall freely, is acted upon the force of gravitational attraction between that body and the earth, and is directed toward the center of the earth.

## How is acceleration of an object in free fall tested?

This acceleration of a falling object can be tested using a Behr Free-Fall apparatus to conduct a free fall experiment. When an object is falling and the only force acting on this object is gravity, then the object is said to be in free fall.
