The acceleration (g) of objects towards the earths surface is related to the acceleration (a) along the inclined plane by where is the angle of inclination.ĬonclusionThe acceleration due to force of gravity was determined by timing the positions of the track up and down an inclined plane.
According to Newton’s laws of motion, an object with an initial velocity of and a constant acceleration can be described by equation : Where is the constant acceleration and is the displacement of the object at any given time?įor an object under free fall, the initial velocity is always zero hence equation can be modified as below to describe this motion 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 change in velocity and is the time taken.

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. In this experiment, earth’s gravitational field strength was determined by using motion detector. G was experimentally determined as which was lower than the theoretical.IntroductionIt is well known that every object on the earth’s surface experiences a downward force due to the earth’s gravitational field.ĭue to this force of gravity, all objects above the earth’s surface will fall towards the earth’s center with a constant acceleration.
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.
