Sadie D. Hood Lab 8: Moment of Inertia Partner: Florence Doval Due 16 November 2011 Aims: To use a centripetal force apparatus to calculate the moment of inertia of rotating weights‚ using theories derived from ideas of energy transfer (Im = MR2 (g/2h)(t2-t02)) and point mass appoximation (m1r12 + m2r22). Set Up Procedure First we measured the weights of two masses and wingnuts that secure them. Then we placed one of the masses on the very end of a horizontal rod on the centripetal force apparatus

person‚ the easier it will be to stop. We all experience this every day. The reason for this‚ is because of the inertia of the moving object. An object will continue to move at a constant velocity unless acted upon on an external force. The magnitude of this force is dependent on the weight of the object. It makes logical sense to think more mass will require more energy. The inertia of an object is it’s resistance to change in motion‚ if an object is stationary‚ it will stay stationary. If an object

1. Thermal inertia is a measure of the thermal mass and the velocity of the thermal wave which controls the surface temperature of a material. In heat transfer‚ a higher value of the volumetric heat capacity means a longer time for the system to reach equilibrium. 2. The ocean acts as a massive heat-retaining solar panel. 3. Salinity‚ temperature and depth all affect the density of seawater. 4. A pycnocline is the cline or layer where the density gradient (∂ρ⁄∂z) is greatest within a body of water

I will evaluate my serve in regards to three major biomechanical principals‚ force & motion‚ momentum & inertia and projectile motion. (Hustler‚ 2012) Force is the change in the velocity of an object. Force changes when the objects motion changes usually by the pushing and pulling of the motion on that object. Force incorporates the law of acceleration ‘The

speeds are on earth. Newton’s first law is most commonly referred to as the law of inertia. The law states that an object that is at rest will stay at rest unless an unbalanced force acts upon it‚ and vice-versa. If an object is moving and there is no force to move the object in a different direction‚ then the said object will move in the path it’s in for an indefinite period of time. Newton’s law of inertia is only relative to what people experience on earth‚ though it is still considered

fragment of the car. This in return prevents the passenger from flying forward when the vehicle comes to a halt suddenly in case of a collision or rapid deceleration. This situation can be better explained with Isaac Newton’s 1st law of motion regarding inertia; an object in motion continues in motion with the same speed and direction unless acted upon by an unbalanced force. Suppose the car is the object in motion. As the car collides with another object or if the car comes to an abrupt stop‚ the brakes
