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

Acceleration of Gravity Using Smart Timers: To calculate the acceleration of gravity using the Smart Timers Steven Ge AP Physics B1‚ Per. 7‚ JSerra Catholic High School Advisor: Mr. Darling‚ Dana. Sep 11‚ 2014 Abstract The purpose of this lab is to calculate the acceleration of gravity using the Smart Timers. Drops of ball of equal size and start drops at one hundred centimeter height‚ the amount of time was counted used the Smart Timers. Repeat the same procedure

Finding the Acceleration of a Ball Problem Statement: How does the height of a ramp that is comprised of two parallel rulers affect the speed of a steel ball bearing rolling down it? Hypothesis: If the steepness of the ramp based on the amount of books propping it up are increased‚ then the steel ball bearings’ speed will increase. Materials: 2 wooden meter sticks 1 steel ball bearing 5 workbooks A roll of masking tape A stopwatch A smooth‚ long surface (preferably a table) Procedures: Arrange

in Lesson 1 is acceleration. An often confused quantity‚ acceleration has a meaning much different than the meaning associated with it by sports announcers and other individuals. The definition of acceleration is: Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity. Sports announcers will occasionally say that a person is accelerating if he/she is moving fast. Yet acceleration has nothing to

between mass and acceleration Stage 1 - Planning Title: Investigating acceleration – How does changing the mass of an object change its acceleration? Introduction: As the speed of moving object and rate‚ the forces acting on the object‚ the mass of the object‚ and gravitational force of it might affect the acceleration‚ I will investigate about the mass of the object. Aim: I will try to answer the question “How does changing the mass of an object change its acceleration?” which is to find

ACCELERATION: Good afternoon everyone! Our group will discuss about acceleration. But before that‚ what is acceleration? Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity. People will occasionally say that a person is accelerating if he/she is moving fast. Yet acceleration has nothing to do with going fast. A person can be moving very fast and still not be accelerating. Acceleration

Aim: To find the mass in grams (m) of a paperclip. Apparatus: Procedure: 1. Using a piece of string‚ the external circumference(C) of the small test tube was found and was then used to find A ‚ the cross sectional area of the small test tube A=C24π . 2. The beaker was placed under the test tube after it was clamped on the retort stand to collect excess water. The large test tube was filled with water. After which‚ the small test tube which had a fitted scale was placed inside to float
