Session 2015/2016 Chapter (2.1 - 2.6‚ 3.3 - 3.4) Week 3 1. Sketch a velocity versus time and displacement versus time for a car approaching a red traffic light and then leaves it as the light turn green. 2. Jimmy took 8 hrs to drive his Civic from KL to Kota Bharu which was about 400 km away. What was the average speed of Jimmy in km/h? Why‚ in this case was the term average speed used over velocity? 3. A ball rolls with a velocity of 20 m/s on the ground and comes to a stop in 3 minutes. (a) Determine

Lab 4 Projectile Motion Sai Moua Purpose: The purpose of this lab was to define what the initial velocity of the ball when it is launched out of the pipe. Our next objective is to determine at what angle that the ball will be ejected at the maximum range. Lastly‚ we predict and confirm the range before we launch the ball at a certain angle. Theory: Projectile motion according to Dr. James S. Walker is defined as‚ “the motion of objects that are initially launched –or “projected”- and that

purpose of this experiment is to determine if the weight of a certain object affects the velocity of the object when it hits the ground. Hypothesis: If the Buick is projected in the air at the same angle as the other objects‚ then it will have a higher velocity compared to a tank shell‚ a golf ball‚ a baseball‚ a bowling ball‚ a football‚ a pumpkin‚ an adult human‚ and a piano. Introduction: In physics‚ velocity is often defined as the speed. Gravity is the amount of force that acts upon an object

Both’ for Velocity and Acceleration at the top of the page. Now click and drag the red ball around the screen. Make 3 observations about the blue and green arrows (also called vectors) as you drag the ball around. When the ball is stopped there isn’t any changes in the placement of the ball. This means that there is zero velocity at that time. 2) Which color vector (arrow) represents velocity and which one represents acceleration? How can you tell? The green arrow represents velocity and the

It is known that the “San Francisco Bay/Sacramento-San Joaquin River Delta” is one of the biggest “estuary on the West Coast of the U.S.”. Therefore‚ will be expanding on this topic. As I go in detail in the situations that the “Delta”. In addition‚ to the objectives that have been recognized through the years. Furthermore‚ the projects that have come about‚ in order to be able to solve the crisis of the “Delta”. Then know if the problem can really be solved or what should be done. How the “delta”

Projectile Motion Objectives: The purpose of this experiment is to examine the projectile motion of a ball launched horizontally. The initial velocity will be calculated. The range of the ball will be measured. Theory: Horizontal launch of the ball allows computing the initial velocity v0 by measuring the height of the launch and the distance traveled by the ball: h=‚ s=v0 ∙ t Solving these parametric equations for v0 gives us: 0=s Where h and s are defined from the

measurements. Secondly‚ uniform motion occurs only when an object travels at a constant velocity. By looking at the velocity is a function of time graph‚ we can tell that the best fit line is not a horizontal line‚ which means that the velocities are not the same‚ which also proves that the movement of the puck is not in uniform motion. Lastly‚ acceleration is determined by calculating the slope of the line on a velocity as a function of time graph which is 0.9ms-2. Acceleration indicates the motion of

Objective: In this lab we will compare different parameters of a launched projectile. This includes time of flight‚ initial velocity‚ initial vertical velocity‚ initial horizontal velocity‚ range‚ time of max height. All these data points are collected for 30°‚ 40°‚ 45°‚ 50°‚ 60°‚ 70°. Date for the 0° angle is was only initial velocity‚ and time of flight. We will then study the relationship of these data points as a function of launch angle.

When an object (stone‚ spear‚ arrow or bullet) is thrown‚ hurled or shot in the air‚ the object is a PROJECTILE (“Projectile”). The study of projectile is important because it must be realized that they are very much part of man’s daily life then and now. Whether man likes it or not‚ he encounters and uses projectile in his everyday life. Our hunting ancestors threw stones and spears on animals to kill them for their food. In today’s sports‚ balls follow projectile motion such
