The Relationship Involving Acceleration‚ Net Force‚ and Mass Giho Park Purpose The purpose of this lab investigation is to observe the relationship among the net force‚ mass‚ and acceleration of an object. Hypothesis/Prediction Part A If the net force increases with a constant mass‚ then the acceleration would increase‚ because the force would push the object to increase the velocity. Part B If the mass of the cart increases with a constant net force‚ then the acceleration would

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

You rub balloons in your hair and then hang them like in the picture below. Explain why you think they move apart and what might affect how far apart they get. A balloon becomes negatively charged when it is rubbed on a person’s hair. This occurs because all the protons and neutrons leave the balloon and attach

and repeat the steps above after you’ve let the compass stabilize. 11. Click on the electromagnet tab. Place the compass on the left side of the coil so that the compass center lies along the axis of the coil. (The y-component of the magnetic field is zero along the axis of the coil.) 12. Move the compass along a semicircular path above the coil until you’ve put it on the opposite side of the coil. Describe what happens to the compass needle. 13. Move the compass along a semicircular

Science in the Big City: Exploring Career Opportunities in the Natural and Physical Sciences New York City May 13-18‚ 2014 Students in the Natural Sciences at the University of Houston-Downtown are generally accomplished and motivated students with strong interests in science. However‚ students typically have a very limited perception of the science careers available to them outside of medicine. To educate students as to the array of potential careers available in the sciences (not medicine)

Introduction The purpose of this lab is to examine the motion of an electron‚ when it encounters a constant magnetic and electric field. We will also observe when the electric field and magnetic field will cancel each other out. This will lead to the electron having no net force acting upon it. By adjusting the values for the magnetic and electric fields‚ we will be able to check the different paths the electron follows. From this data we will be able to calculate the charge-to-mass ratio. Then

The moment of inertia is a measure of an object’s resistance to changes in its rotation. It must be very specific to the chosen axis of rotation. Also‚ it is specific to the mass and shape of the object‚ including the way that is mass is distributed in the object. Moment of inertia is usually quantified in kgm2. An object’s where the mass is concentrated very close to the center of axis of rotation will be easier to spin than an object of identical mass with the mass concentrated far from the axis
