To graphically analyze motion, two graphs are commonly used: Displacement vs. Time and Velocity vs. Time. These two graphs provide significant information about motion including distance/displacement, speed/velocity, and acceleration. The displacement and acceleration of a moving body can be obtained from its Velocity vs. Time graph by respectively finding the area and the slope of the graph.

Summary Questions

1)Describe the meaning of the slopes of the graphs you obtained in Part III. The slope of the Displacement vs. Time graph (0.6 m/s) represents the velocity of the moving cart at 0.8 seconds. The slope of the Velocity vs. Time graph (0.3 m/s2) represents the acceleration of the moving cart at 0.8 seconds.

2)Describe the motion of the cart based on your result from the Velocity vs. Time graph. Based on the Velocity vs. Time graph, the cart is decelerating because the slope decreases as time passes and the slope represents acceleration/deceleration in a Velocity vs. Time graph.

Abstract
This experiment measures the study of motion by observing the force of gravity acting solely upon an object, and also measures reaction time. If an object is in free fall, the only force acting upon it is gravity. The object used in this experiment was a golf ball that provided some acceleration when dropped. A sensor positioned underneath a table recorded the golf...

Conclusion
The purpose of the experiment was to investigate simple elastic and inelastic collisions to study the conservation of momentum and energy concepts. The objective of the lab was met since the validity of the Law of Conservation of Momentum was confirmed by determining the relationship of energy and momentum conservation between inelastic and elastic collisions by utilizing percent discrepancy...

Density
Abstract
This experiment was conducted in order to determine the density of the Aluminum metal samples provided in the lab. Specific tools such as the vernier caliper and balance scale were used to measure and record the values found. Given that density is a measurement of mass over volume, both of these quantities would have to be determined experimentally, prior to proceeding with...

...object’s velocity.
Momentum = mass x velocity
p = m v
Momentum can also be defined as inertia in motion. To have momentum, the object must be moving. Momentum tells how hard it is to get something to stop or to change directions. Every moving object has momentum and any object with momentum is going to be hard to stop. To stop such an object, it is necessary to apply a force against its motion for a given period of time. The more momentum the object has, the...
