Lab Conclusion – Acceleration

When comparing the average speed results from part two of the lab and the definition of acceleration, you find similarities between the two. First, average speed is distance divided by time, and we use it to describe the motion of an object moving at changing speeds. We can see this from our lab results from the average speed of the marble traveling down the ramp, because it picks up speed. When the marble is released at the top of the ramp, the ball doesn’t have the same momentum as it does towards the end of the ramp. Gravity and friction also affect the speed of the marble going down the ramp. Gravity affects it because it forces the marble down…

Measurement of Free-Fall Acceleration

Introduction Galileo Galilei (1564-1642), the man first accredited with the correct notion of free-fall with uniform acceleration, stated that ‘if one were to remove entirely the resistance of the medium, all materials would descend with equal speed.’ Today, this statement holds true for all objects in free-fall near the Earth’s surface. The purpose of this experiment is to verify Galileo’s assertion that acceleration is constant. In addition, the magnitude of acceleration will be calculated. Theory By definition, acceleration is the rate of change of velocity with respect to time. Instantaneous acceleration is the derivative of velocity with respect to time. a(t) = dv / dt. Average acceleration is the change in velocity during a time interval, Dt, divided by the…

Seek feedback

Seek feedback from people that you know about a task that you regularly carry out. This might be a task that you carry out at work. If so, you should seek feedback from employees, clients and colleagues. Alternately, this might be a task you carry out in your day-to-day life, such as driving a car or making dinner. If so you should seek feedback from friends and family members. How would you ensure that the feedback you receive is useful? How would you use this feedback to identify and develop ways to improve competence in the task you have selected? I have recently been learning to drive a manual car and have been getting lots of feedback from my instructor…

Moment of Inertia

Abstract The moment of inertia, or also known as the rotational inertia, is the rotational analog of a rigid body to a linear or an angular motion. It is one of the fundamentals of the dynamics of rotational motion. The moment of inertia must always be in a specified chosen axis of rotation. The point of motion is basically defined as the relationship between mass and the perpendicular distance to the rotational axis. KEYWORDS: Moment of Inertia, Rigid body, Angular motion, Axis of rotation Introduction Moment of inertia is always defined with respect to a specific axis of rotation. The mass moment of inertia with respect to an axis is also defined as the product of the mass times the…

Projectile Motion Lab Report

Background Acceleration is constant at 9.8 m/s2 because of the force of gravity. For experiment 1 the velocity will be calculated by measuring “x” and “y” and using the combined x & y equations to solve for Vo. Vo= x⌠g/2y. For experiment 2 the range equation for distance x=R is applicable since the launch and landing elevations are the same. R=(Vo2sin2ᶿ)/g Objective The objective of experiment one is to determine the distance a falling object will travel when the launch height is changed. The objective of experiment two is to observe the distance, x=R, a projectile will travel when the launch angle is changed. Acceleration is constant at 9.8 m/s2 in all the experiments due to gravity. Hypothesis Experiment 1:…
