Moment of inertia

Angular momentum can affect the rotational inertia due to the fact that angular moment is always conserved unless there is an external force. Angular momentum can include the rotating figure skater, my coach, and the point on the ice which is the toe pick of the ice skate’s blade. With the assumption that there is no friction on the ice, rotational inertia is a form of resistance during rotation in a counterclockwise direction. The skater’s body becomes the axis of rotation. Rotational inertia is also known as…

of a mini torsion device may be its size. Depending on the design of the overall device, the radius of the inclinometer might be too large. The radius of the digital inclinometer above is 42 mm, which is about 7-8 times the diameter of the sample. A lab that used inclinometers to measure the angle of twist also found that the response of the inclinometer was sluggish5. Using a different inclinometer than the one used in the lab might correct this problem. Torsion Load Cell Another device that…

Newton’s three laws of motion essay Isaac Newton was an English physicist, mathematician, astronomer, and natural philosopher who lived in the 17th century. One of his accomplishments was coming up with three laws of motion that can be used to explain how and why stuff move. These laws that Newton came up with are still used today. Newton’s first law of motion states that “an object in motion will stay in motion, and an object at rest will stay at rest unless an unbalanced force acts on it”.…

steel beam. The hollow aluminum box trendline had the lowest slope of any of the tested beams at .000016x, which is under half that of the steel beam. Considering the rectangular aluminum beam experienced the greatest deflection, shape is observed to have a large effect on the measured deflection. This is significant because a certain shape may be better than other shapes to produce the least amount of deflection. The differences and similarities seen in the slopes in Figure 1 are caused…

Newton's three laws of motion consist of information about gravity, force and acceleration. The law’s where written by Newton in 1666. Each law explains a different theory about how gravity works. The first law talks about why objects stay in motion or rest unless an unbalanced force is acted upon that object. The next law explains how force equals acceleration. The third law talks about how if any action is created there is a equal and opposite reaction that appears. Each one of these laws…

The scientist, Sir Isaac Newton, helped to organize the thinking about forces by formulating three laws. In his book Newton describes his three laws of motion. Newton’s Laws are all around us. To prove this, you will conduct 14 different activities showing everyday examples of these laws. Lab Procedure You will start at a lab station and then move from station to station until you have completed all 14 activities. You will have 3minutes to do the activity at each lab station. Perform the…

This is achieved by using big muscles before small muscles, from the initial start of the swing too the follow through phase at the end. This was applied to golf through sequenced movements to accelerate my swing and hit the ball with as much velocity as possible. Ideally larger muscles such as quads and hamstrings will be used first and then progress into smaller muscles like biceps and triceps. This principle is applied is called inertia. Inertia states that larger and bigger masses take…

you go swimming it is important to know what each body part is doing. And where it is doing while you are swimming. Your body does a lot of moving while swimming. It uses a lot of muscles. Swimming is a great exercise for you, it relaxes your muscles. (agency for instructional technology , 2010) The best way to propel the body forward through the water is to pull the hand directly backwards. Freestyle begins with a catch and a motion, which allows the swimmer’s hand to engage the water. When…

Newton’s Laws Sir Isaac Newton, the man who developed the first theories of gravitation, also introduced the three laws of motion. These laws essentially changed the field of physics in an astounding manner – it paved the way to modern science. Let’s look at these laws in some more detail: Newton’s first law: It states that an object will remain at rest or in a uniform motion, unless an external force acts on it. This is basically also the definition for inertia. In other words, the state of…

Three tests are done through a Gizmo to determine how radius, mass, and velocity affects centripetal acceleration of an object undergoing uniform motion. The results show centripetal acceleration is affected by radius and velocity but not mass. It gives a better understanding to why objects in uniform motion accelerate towards the centre of a circle. Introduction The purpose of this lab is to determine how the radius, mass and speed of an object can affect the centripetal acceleration of the…
