Measuring the acceleration due to gravity in the lab


Our aim was to find the acceleration due to gravity in the laboratory.


The distance between the ceiling and the floor (h) was measured.  A rubber was then dropped from the

Average Time = Sum of all times

 Number of Times

= (0.47+0.45+0.71+0.55+0.5+0.71+0.4+0.46+0.58+0.56)


= 5.85


= 0.59 sec (to 2 dp)

H = height of the drop

T = time taken

Acceleration due to gravity = 2H




= 5.18


= 14.88 m/s2 (to 2 dp)


The results circled in the table are anomalous.  There was a wide range of results, from 0.4 to 0.71.

The experiment should be repeated in exactly the same fashion as before, but with the changes outlined above implemented.  This would give more accurate results.  It should then be repeated in the same way as this, but with a denser object of the same dimensions.  This would show that the acceleration was due to gravity and not the mass of the object.  One more experiment should be undertaken with the same stipulations but an increased dropping height.  This would show that the acceleration is the same no matter how high the object is dropped from.

    and the experimental value: The experimental value is smaller than theoretical value, since there is some source of error in this experiment. Firstly, the angle of oscillation may be not small enough, it may be larger than 10, small oscillation approximation is not appropriate.

    The force is rapidly spread throughout the incompressible water. Time Force A B C At times B and C the second and third blades strike and the effect is similar. Over time, water does not experience equal force. This jerky distribution of force with time may lead to eddies forming,

  2. Objectives: To determine the center of gravity of a body of irregular shapes

    To solve this error, we have two solutions. Firstly, we can use a large block that is placed behind the irregularly shaped board when it is hung on the pin. It can give the support for us to mark the intersection point on the edges.

  1. Determination of the acceleration due to gravity (g) by free fall.

    To make a test drop, insert a steel ball into the Release Mechanism so that it is positioned on the contact screw and aligned with the hole in the release plate. Close the Release Mechanism by pushing on the dowel pin, which clamps the release plate on the ball, and

  2. Experiment to Find Acceleration due to Gravity

    and m = mass (in kg) Normal Force, The normal force is the support force exerted upon an object which is in contact with another stable object. For example, if a book is resting upon a surface, then the surface is exerting an upward force upon the book in order to support the weight of the book.

  1. To determine the acceleration of gravity in a free fall experiment.

    0.154 0.152 0.023 The collected data will be presented graphically to find a value for gravity, this can be done by using an equation for constant acceleration, where x = displacement, u = initial velocity, a = acceleration, t = time x = ut + ( at� It is assumed

  2. Experiment to find the acceleration due to gravity using free fall.

    All following material is taken from Explaining Physics A-Level Edition by Stephen Pople. Gravity is a force of attraction between any two masses. This force is unusual as it is the only force discovered that has no repulsive effect unlike for example, magnetism which can attract and repel other masses.
