Damped Harmonic Motion Erica Partner: Steven November 8‚ 2012 Abstract During this experiment‚ the effects that the size of an object had on air resistance were observed and determined. To do this‚ a spring was set up with a circular object hanging at the end. After the spring constant of 9.0312 N/m was measured‚ equations were used to determine a calculated frequency‚ that being 7.252 Hz. Four trials—each with a different sized‚ same massed object—took place where the object was pulled

ACTIVITY: THE CAT’S MEOW / MILK CO-MOTION PURPOSE: To observe the interaction of detergent with the fat of the milk and food color 1. Provide a possible explanation of phenomenon you observed based on the result of your experiment. When food color is added to milk‚ it floats because it is less dense than milk. The non-polar fat in the milk prevents the food color from spreading‚ as it cannot participate in hydrogen bonding with water. When detergent is added to milk and the food color‚ the

Two bricks are resting on edge of the lab table. Shirley Sheshort stands on her toes and spots the two bricks. She acquires an intense desire to know which of the two bricks are most massive. Since Shirley is vertically challenged‚ she is unable to reach high enough and lift the bricks; she

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. In this experiment‚ when one projects an object in the air‚ gravity acts upon the object causing it to come down. However‚ the answer that I am trying to discover is if the weight of the object affects

object slows down‚ then they are in opposite directions. Any object that is traveling in a vertical direction also experiences acceleration due to gravity. Left: Object travels to left and speeds up. Down: Object is tossed upward. A ball is tossed up into the air with a velocity of 50 m/s. The figure to the left shows the position of the ball at equal time intervals on its upward travel. Answer the following questions regarding the instantaneous velocity and acceleration of the ball: True:

of a process called motion capture. Motion capture has been around since the late 1970s‚ where it was then called rotoscoping and was used by Walt Disney in the film Snow White (Sturman). To begin with‚ the term “motion capture” actually has many different names‚ such as mocap‚ performance animation‚ performance capture‚ virtual theater‚ digital puppetry‚ real-time animation‚ and the favorite among traditional key frame animators is “The Devil’s Rotoscope” (Furniss).

If the motion is two-dimensional and lies in a plane‚ some representations include: (1) recording x and y coordinates of the object at different times in a data table; (2) displaying the object’s x and y locations at regular time intervals on a diagram; (3) drawing vectors showing displacement‚ velocity
