This lab report defines what uniform acceleration is and how to calculate uniform acceleration of a cart rolling down a ramp at different angles and elevations. The experiment will be performed by setting the cart on the track against the end stop and then record this final position on the steel ramp ten times. Once the results are found you can calculate the percent error of the uncertainty values. The uncertainty value is the acceleration of the cart falling down. That value will be compared to the gravity value to see how closely related they are.
Introduction
During the 14th century, the French scholar Nicole Oresme studied the mathematical properties of uniformly accelerated motion. He had little interest in whether that kind of motion could be observed in the realm of actual human existence, but he did discover that, if a particle is uniformly accelerated, its speed increases in direct proportion to time, and the distance it traverses is proportional to the square of the time spent accelerating. Two centuries later, Galileo repeated these same mathematical discoveries (perhaps independently) and, just as important, determined that this kind of motion is actually uniform acceleration. So basically Uniform, or constant, acceleration is a type of motion in which the velocity of an object
changes equal amounts in equal time periods.
Theoretical Background
Anobject with a mass (m) travels with uniform velocity and uniform acceleration i.e. an object moving with a uniform or constant velocity or acceleration. The purpose of this experiment is to study the relationships between position, velocity, and acceleration in linear motion when the object moves with a constant acceleration (inclined plane). To find out the acceleration, release the cart from rest and
