Physics midterm - Essay Example

Physics Assignment Physics Assignment In studying the motion that results when an object moves under the influence of gravitythe following principles have applied. The first principal used is Newton’s law of universal gravitation. It states that two objects exert a force of attraction on each other, and the force experienced is along the line joining the two objects. The second principal is the Newton’s laws of motion that have been used to calculate the displacement, velocity and acceleration of objects under the influence of gravity either in free fall or in inclined motion.

The experiment intends to answer the following questions: How does the position and velocity change with time? How does the weight of an object affect its motion? And finally what is the effect of other forces other than gravity on the objects motion? The following measurements were taken in the lab: The objects displacement over time during the fall and the Carts displacement over time starting from rest. The time interval for the cart for five different inclination angles and the time interval when the angle of inclination for the cart is constant, and the mass is varied were noted.

The measurement taken in the lab relate to the principals used in the experiment. Using the measurements and the basic kinematic equations we have calculated displacement, velocity and acceleration. Therefore the motion of the object in free fall and an inclined plane has been described. The lab relates to the material covered in class since using the data we have confirmed the expected results from theoretical analysis using the actual results. Real world applications of this lab include orbit calculations, explorations of oceans resources, satellite launch, exploration of natural resources and isometric height measurements.
