#Freefall and acceleration due to gravity lab free#

The radius of the Earth, R = 6.4 × 10 6 m The universal gravitational constant = G = 6.67 × 10 – 11 N m 2/kg 2 The acceleration due to gravity on the Earth is given by, G = (GM/r 2) Acceleration due to the gravity of the Earth: This means that the ball has been accelerating (increasing its velocity with time) throughout its motion. Therefore, there has been an increase in velocity from the initial point A and another point B in the motion of the ball. And, at point B, it is moving, which means it has some velocity. The ball was dropped at point A, which means it had zero velocity at that point. A is the initial point of the motion, and B is located somewhere in the path.

Explanation: Free fall- A uniformly accelerated motionĬonsider two points A and B, in the path of a ball falling from the top of a building, as shown in figure 3.1 below.

An example of a freely falling body without air resistance is the revolution of the Moon around the Earth, as outer space has no air. Such a motion in which the body moves under the action of gravity alone is called free fall. If the upward air resistance is neglected, the body moves only under the action of gravity. The bodies falling towards the Earth experience two forces, namely the downward gravitational force and the upward air resistance (generally small). The attractive force varies directly as the product of the masses and inversely as the square of the distance between them.Yes, there is a force of attraction between any two bodies in this universe.The acceleration gained by the Earth is negligibly small for its movement to be noticeable.A body falling towards the Earth also pulls the Earth towards itself.
