Inertia (Law of Inertia) Name _____________________ Section _________ Date ______ The law of acceleration explains how a net force makes a mass accelerate. It shows how the magnitude of the acceleration depends on the magnitude of the force (directly proportional) and on the magnitude of the mass (inversely proportional). Acceleration happens only when there is an unbalanced force. Where All Forces Are Balanced No change of velocity occurs when the forces acting a body are balanced

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

Flywheel energy storage works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy. The energy is converted back by slowing down the flywheel.Flywheel energy storage system is one form of energy storage devices. It is basically a rechargeable battery. It is used to absorb electric energy from a source‚ store it as kinetic energy of rotation‚ and then deliver it to a load at the appropriate time‚ in the form that meets the load needs

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

Inertia Inertia is the tendency for a body to either remain at rest or move in a straight line at a constant speed‚ unless acted up by an unbalanced force. In both cases‚ the item has an acceleration of zero. Inertia is not a force‚ but rather a resistance to a change in velocity. In other words‚ the object wants to stay put or stay constant‚ and inertia is what happens when a force gives it acceleration. An example of inertia in the physical world happens while riding in a car. The driver

Thermodynamics Inertia Laboratory Report Summary The objective of this report is to find the Moment of Inertia of a disc by means of investigating the use of rotational motion. We then used the results of the experiments to plot a graph showing the relationship between the mass of the weight with the time taken by load to pass the distance of length of the string. Three different size discs were used in these experiments to determine the influence the size of a disc will have on its Moment of inertia

Inertia is the tendency of something to go unchanged; it follows that cultural inertia‚ a topic in sociology‚ is the resistance for a culture to change. Cultural inertia may work to prevent a more desirable or efficient outcome for society. Nevertheless‚ there are often attempts to break free from cultural inertia to increase the quality of life for a group of people. Soylent is one of these attempts. Rhinehart and the other makers of Soylent are seeking to streamline our daily lives by partially

Prac Report – Investigating Parachutes Experiment Aim: To measure how the size of a parachute t’s surface area affects the parachute’s speed‚ acceleration and time of flight. Hypothesis: A parachute with a larger surface area would fall slower due to that fact there would be a higher level of drag‚ or in other words more air resistance. Materials: * Sturdy garbage bags * Metric ruler * Scissors * Washers * Twist ties * Light-weight string * Stopwatch Method:

the first day of kindergarden. It was a sunny day in January 2001‚ I was all alone with no one to talk to. Scared and nervous‚ but she walked over and started talking to me. I knew we would be best friend. We were closer than ever and we spent every moment together. Ever since then‚ it had been nothing but a strong friendship. On a clear summer night‚ I was staring up at the sparkling sky‚ swaying on the playground swing. My best friend of 12 years sat quietly on the swing next to me. Suddenly‚ there
