Acceleration

Renatta Oyles car driving down 84th street like she is has a velocity of a leftward direction and a leftward direction for acceleration. Velocity is defined as the speed of an object that is going in a certain direction. In this case her velocity is in a leftward direction because she is starting on the right and her car is moving to the left. She is starting on the right because in the diagram is shows that she was stopped on the right and those are the first dots in the diagram because she…

and y components of acceleration when the projectile is in motion? Call y positive upwards. The x component of acceleration is zero because projectiles have a constant velocity, resulting in no horizontal acceleration. The y component of acceleration is a constant -9.8 m/s2 in relation to the gravitational force acting on the projectile. Why does the x component of velocity remain constant? The x component of velocity remains constant because since the horizontal acceleration is 0, then the x…

As the height of the ramp increased, the speed, velocity, and acceleration also increased. In Run 1, the height of the ramp was highest at 5 textbooks. Evidence: The speed and velocity of the car in this lab are essentially the same because the total distance traveled is equal to the total displacement of the car. In Run 5, the ramp had the lowest height of one textbook. Using the slope of the position versus time graph, the speed of the car from Run 5 to Run 1 was calculated to 0.439 m/s, 0.745…

Motion Table of Contents Background Information 1 Research Question 1 Hypothesis 1 Variables 1 Materials 2 Procedure 3 Background Information Motion is the change of position of an object with respect to time. The physical quantities velocity, acceleration, displacement, time and speed are used in the study of motion. If an object does not change position with respect to time, it is considered as stationary. Note that if an object is motionless, it does not necessarily mean that there is no…

Newton’s second law of motion demonstrates the relationship between force, mass, and acceleration, explaining that the force is equal to the mass of an object times the acceleration. If we apply this rule to football, it can be concluded that although the mass (of the football player) is unlikely to be changed, the acceleration can be. The new Zero1 helmet was specifically designed to address the acceleration a player experiences during impact in order to reduce these sheering forces (VICIS,…

Human walking has been studied extensively with the assumption of steady-state gait. However, we rarely walk under steady-state conditions. Acceleration and deceleration, obstacle negotiation, disturbance rejection and turning are all examples of behavior that require modulation of walking speed which is in turn driven by transient changes in muscle activations. A few studies in recent years have explored characteristics of transient walking [1], [2], [3]. It has been suggested that control of…

Summary of Report The Templeton National Report on Acceleration titled A Nation Deceived: How Schools Hold Back America’s Brightest Students discusses current issues with the education system in the United States. This report also argues for systematic changes to be made that benefits children and adolescents of all developmental levels, specifically those that are academically gifted. Three authors, with educational career backgrounds, contributed to this report and recognize that students,…

INTRODUCTION Can the magnitude of gravity be found by measuring the period in relation to the length of the string of an oscillating pendulum? The aim with this lab was for us to gain a greater understanding in the area of oscillations and simple harmonic motion. Also to determine if the use of a pendulum is a good strategy for measuring the gravity. I found this experiment to be very interesting since I’ve seen and used pendulums a lot before, but I have never really reflected on why they…

Experiment-1 Simple pendulum: Aim: The main aim of this simple pendulum experiment is to investigate the relationship between the time period of a simple pendulum (oscillation) and the effective length (total length) of the simple pendulum. The three variables in Experiment-1 Simple pendulum: Independent variable: The independent variable in this experiment is the length of the string of the pendulum that could be changed. Dependent variable: The dependent variable is the time period for one…

Introduction: In this lab, we will be analyzing the effect of force on the acceleration of a cart both with and without added mass. In a sense we will be seeking to confirm Newton's second law of motion. As stated in the second law of motion, force is equal to mass multiplied by the acceleration or F=ma. When we increase the mass we would expect the acceleration to decrease when force is the same as the rewritten equation would be f/m=a. In this case it is important to specify the difference…
