Notes: Vector Resolution. A vector may be broken into its two components, in the horizontal and vertical direction Given an original vector A, its components would be: A x parallel to the x-axis A y parallel to the y-axis. Vector Resolution. original vector = vector sum of components

ByHorizontal Projectiles. Projectile. An object in motion where the only force acting on it is gravity. A dropped ball A kicked football A diver leaving a springboard A shot-put throw A satellite. Independence of X and Y.

ByProjectile Motion. Projectile. An object that moves through the air only under the influence of gravity after an initial thrust For simplicity , we’ll use 9.8 m/s 2 for gravity. Trajectory – path of a projectile.

ByProblems from old midterm. 1. In this graph of displacement versus time, what is the average velocity in going from point A to point H in m/s? (Assume that the vertical axis is given in meters and that the horizon- tal axis is given in seconds) A) 0.286 B) 0.323 C) 0.365 D) 0.412

By7-2 Projectile Motion. Independence of Motion in 2-D. Projectile is an object that has been given an intial thrust (ignore air resistance) Football, Bullet, Baseball Moves through the air under the force of gravity Path is called Trajectory

ByWork . Page 168 . What is work? . A little different from what we’re use to in our everyday lives When you hear the word work , what do you think of? . Scientific Definition of Work . A force that causes a displacement on an object does work on the object

ByTry this problem. Five forces act on an object: the first, 60 N at 90 degrees; the second 40 N at 0 degrees; the third 80 N at 270 degrees; the forth 40 N at 180 degrees; the fifth 50 N at 60 degrees. What is the magnitude and direction of a sixth force that produces equilibrium of the object?.

ByVECTORS. A vector is a quantity that has both magnitude and direction. It is represented by an arrow. The length of the vector represents the magnitude and the arrow indicates the direction of the vector. Blue and orange vectors have same magnitude but different direction.

ByWednesday – November 7. Review Exam on Friday. REVIEW. You are allowed on flash card. I will NOT provide formulas. What is the resultant of a pair of forces 100N upward and 75N downwards? 25N up. Why is speed scalar and velocity vector? Speed is only a number.

ByS outh America Riometer Network (SARINET) Kazuo Makita (Takushoku University, Japan ). We study upper atmosphere phenomena in South Atlantic Geomagnetic Anomaly ( SAGA) since 1997. So far, we installed several instruments at more than 10 stations in South America.

ByAPPLICATION OF FORCES. IMPULSE. Quite simply the time it takes a force to be applied to an object or body and is often related to a change in momentum. In sport, impulse can be used to add speed to a body or object, or slow them down on impact. Impulse = Force x Time

ByProjectile Motion. Falling things, and rockets ‘n’ that…. Projectile Motion. This involves any objects under the influence of gravity. O bjects which are dropped (not travelling horizontally) and O bjects which are launched (with a horizontal component).

ByFalling Objects. SNAP Guide. Read page 130; and answer all 7 questions on that page (‘net research may be required) Do Q1 on page 131 (‘net research may be required) Read page 132. Galileo:.

ByProjectile Motion. The motion of an object under gravity if it is not just going straight up or straight down. Components of Vectors. Velocity Vector. θ. Horizontal. θ is the angle of the velocity vector above the horizontal.

ByNon-Horizontally Launched Projectiles. 11/12/2013. The details of motion in each direction have not changed. The parabolic path of the object is altered slightly due to a change in the initial vertical velocity ( v iy ). Consider the following diagrams when answering the questions. 2. 1. 3.
