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

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

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

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

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

or river per unit of time‚ commonly expressed in cubic feet per second. The up-stream and downstream cross-sections were setup using a tape measure and stakes. There were 21 cross-sections in measured intervals. A current meter was used to measure velocity at the same location as each depth measurement at each cross-section that was determined. Also used was the float-Method‚ a length of stream was measured‚ and a start and finish points were sectioned off. Then a float was used to measure how long

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.

Reading Assignment #1: Vector Analysis Textbook Sections that I read: 2.1-3 Important Concepts: An interaction between two objects can be described and measured in terms of two forces. The force is a push or either a pull. There are two types of forces. #1 is a long range force and this force does not require the objects involved to be touching each other. An example of this is when you are holding a magnet away from a refrigerator and you are able to feel the magnetic pull. #2 is a contact force

A motorist drives south at 20.0 m/s for 3.00 min‚ then turns west and travels at 25.0 m/s for 2.00 min‚ and finally travels northwest at 30.0 m/s for 1.00 min. For this 6.00-min trip‚ find (a) the total vector displacement‚ (b) the average speed‚ and (c) the average velocity. Let the positive x axis point east. 2.
