Experiment 9: Maxwell’s Wheel Introduction: The second lab performed on 2/1/12 involved two investigations concerning Maxwell’s wheel. Maxwell’s wheel is an apparatus that consists of a large disk with a long axle. The disk then bound to a support hanging from above with strings attached to each end of the axle. Maxwell’s wheel is considered to be an important apparatus to investigate physical phenomenon’s because it its ability to combine straight line motion and rotation of a rigid body

graph of 2 x distance vs. time squared represents acceleration. It represents acceleration‚ because the line shows that the graph is steadily increasing‚ because of its almost constant slope. As a result‚ the slope of the line is constant‚ and so the acceleration is constant. Additionally‚ to determine an experimental value for acceleration one must find velocity‚ time‚ and then calculate your equation. Then‚ calculate gravity by using the acceleration value and divide it by 0.0043. g=

Find the constant angular acceleration of the centrifuge. -226 rad s-2 3. A machine part rotates at an angular speed of 0.60 rad/s; its speed is then increased to 2.2 rad/s at an angular acceleration of 0.70 rad/s2. Find the angle through which the part rotates before reaching this final speed. 3.2 rad 4. A coin with a diameter of 2.40 cm is dropped

constant speed until acted on again by a larger force that stops it. The second law is Force= mass X acceleration. And the third is all forces act in pairs‚ pretty simple right? Just remember this and the examples and the rest should make more sense. The three laws of motion explain how an object will either stay in motion or what makes it move‚ (law of inertia)‚ Force= mass X acceleration‚ and action and reaction. This essay will basically take the dry basics of the rules and elaborate

The acceleration is often quoted in multiples of g‚ the standard acceleration due to gravity at the Earth’s surface. This distinction is important because two rotors with different diameters running at the same rotational speed will subject samples to different accelerations.

for a body that is undergoing centripetal acceleration. Background Information An object moving in the same direction is not necessarily undergoing acceleration. If the object changes speed while moving in the same direction there is acceleration (or deceleration). On the other hand‚ if the object moves at a constant speed in the same direction‚ there is no acceleration. This does not mean that constant speed always indicates no acceleration‚ however. An object that moves at a constant

Circular Motion and Gravitation Circular motion is everywhere‚ from atoms to galaxies‚ from flagella to Ferris wheels. Two terms are frequently used to describe such motion. In general‚ we say that an object rotates when the axis of rotation lies within the body‚ and that it revolves when the axis is outside it. Thus‚ the Earth rotates on its axis and revolves about the Sun. When a body rotates on its axis‚ all the particles of the body revolve – that is‚ they move in circular paths about
