The acceleration due to force of gravity was determined by timing the positions of the track up and down an inclined plane. The acceleration (g) of objects towards the earths surface is related to the acceleration (a) along the inclined plane by
Where is the change in velocity and is the time taken. Where is the height above the earth’s surface and is a constant acceleration due to the earth’s gravity? The acceleration can also be determined from the change in velocity over time as in this experiment
Where is the constant acceleration and is the displacement of the object at any given time? For an object under free fall, the initial velocity is always zero hence equation can be modified as below to describe this motion
Acceleration due to gravity lab report example series#
The motion detector was used to measure and record a series of position and time of the track moving up and down along an inclined plane and plot the velocity-time and acceleration time graphs.Īccording to Newton’s laws of motion, an object with an initial velocity of and a constant acceleration can be described by equation : In this experiment, earth’s gravitational field strength was determined by using motion detector. Due to this force of gravity, all objects above the earth’s surface will fall towards the earth’s center with a constant acceleration. It is well known that every object on the earth’s surface experiences a downward force due to the earth’s gravitational field. G was experimentally determined as which was lower than the theoretical. A motion detector was used in the lab to study the motion of the track moving along an inclined plane plotting the velocity-time and acceleration-time graphs of the track motion. Motion: Gravitational acceleration Motion: gravitational acceleration The principal aim of this experiment was to determine the acceleration due to the earths gravity.
