Definition. When a body moves exclusively under the influence of the Earth's gravity, it is said to be in freefall. The motion of the ball will be accelerated as a result of an external force acting on it. This free-fall acceleration is also known as acceleration due to gravity. Examples of free fall. A few examples of free fall are listed below.
Weightlessness is a condition of free-fall in which the gravity is cancelled by the inertial force arising from orbital flight or other gravity-negating situations. It is experienced due to the absence of the feeling of weight. It happens in the lack of any contact forces acting on bodies (human body). Q4.
Free fall is defined as a situation in which an object moves only under the influence of gravity. An external force acts on the ball, which accelerates its movement. This acceleration of free fall is also known as gravitational acceleration. Free fall is just a downward movement with no initial force or velocity.
Freefall as the term says, is a body falling freely because of the gravitational pull of our earth. Imagine a body with velocity (v) is falling freely from a height (h) for time (t) seconds because of gravity (g). Free Fall Formulas are articulated as follows: h = (1/2) gt 2. v 2 = 2gh. v = gt.
A free body diagram is a diagram that is modified as the problem is solved. Typically, a free body diagram consists of the following components: A simplified version of the body (most commonly a box) A coordinate system. Forces are represented as arrows pointing in the direction they act on the body. Moments showed as curved arrows pointing in ...

Galileo’s Free Fall Experiment. The most accepted theory of motion in Western philosophy, prior to the Renaissance, was the Aristotelian theory which stated that “In the absence of external power, all objects would come to rest that moving objects only continue to move so long as there is a power inducing them to do so. ” Despite its ...
Weightlessness is a sensation experienced by an individual where there are no external objects touching one’s body. In other words, the sensation of weightlessness exists when all contact forces are removed. These sensations are common to the state of free fall. Q4.
However, the movement of the pendulum is not free fall; it is constrained by the rod or string. The height is written in terms of angle θ and length L. Thus, h = L(1 – cos θ) When θ = 90 0, the pendulum is at the highest point. Then cos 90 0 = 0, and h = L. Therefore, Potential Energy = mgL. When θ = 0 0, the pendulum is at the lowest point.
Mechanical energy is the sum of kinetic energy and potential energy in an object that is used to do a particular work. In other words, it describes the energy of an object because of its motion or position, or both. Let us consider the example of an ideal simple pendulum (friction-less). We can see that the mechanical energy of this system is a ...
