Moment of inertia

A world leading physicist, astronomer, natural philosopher, alchemist, theologian and mathematician, Sir Isaac Newton is known globally for being one of the most influential men to ever live. Newton was born on Christmas day, 1642 in Woolsthrope-by-Colsterworth, United Kingdom where his grandparents raised him. In the beginning Isaac was heavily pressured into being a farmer, however he was so terrible at farming they decided to send him to university. At 19 Isaac attended his first classes at…

Newton’s 3 laws of Motion 1. If a body is as rest it remains at rest or, if it is in motion, it moves with uniform velocity, until it is acted on by a resultant force. 2. Acceleration is dependent on the forces acting upon an object and the mass of the object. Therefore, if the force is increased, the acceleration is increased. And the more mass the object has, the more acceleration decreases. So the resultant force (F) is equal to mass (m) times acceleration (a) (F = ma). 3. For every action,…

1. The following events related to untochable force: (1) coconuts falling from the tree to the ground (2) Attract magnetic iron plates (3) footwear be worn after long use (4) Budi push the beam to shift to the right The above events involving untouchable force is the number of events .... a. 1 and 2 b. 1 and 3 c. 2 and 4 d. 4 2. Amir and Badu are playing tug of war. Amir pull to the left with a force of 200 N while Badu pull to the right by the force of 350 N. resultant force generated is ....…

1. The pendulum of a clock swings back and forth. At what position will its kinetic energy be the greatest? At what position will its kinetic energy equal its potential energy? When the pendulum of a clock swings back and forth, the pendulum reaches its maximum potential energy at the top of the swing, and it reaches its maximum kinetic energy at the bottom of the swing. In the absence of frictional forces, the pendulum’s kinetic energy will be equal to its potential energy at the bottom of the…

The laws of motion include three different laws. The first law of motion is usually called the law of inertia. Basically in this law it means an object will remain at rest (inertia) unless a force acts upon the object. Basically this law is saying that if an object is sitting still or not moving, it will not show any sign of motion unless some type of force actually moves the object. The second…

In conclusion, we can use Newton’s 3 laws of motion to maximize our rockets’ flight time. For Newton’s first law, our hypothesis stated the following: “We can apply Newton’s first law by minimizing the forces that resist motion. The way we will do this is to make the nose cone as smooth and pointy as possible. If the nose cone is too flat on the end, it will not cut through the air very well. The rocket must cut through the air swiftly, this means that resistance will be at its minimum during…

Elements of Orbital Analysis We first derive a general solution of a two-body problem subject to the universal gravitational attraction (Newton’s Law of Universal Gravitation), and then consider special cases of interest for our purpose. 1.4.1. Equation of Motion under Newton’s Law of Gravitation Using the coordinates shown in Figure 1.2, Newton’s Law of Gravitation implies that the two bodies of masses M and m, and the radius vectors r ⃗_M and r ⃗_m , respectively, would exert the…

Proving Newton’s Second Law of Motion Aim: Prove that a (acceleration) is proportional to the net force and inversely proportional to the mass. Background Theory: Sir Isaac Newton presented his three laws of motion in the Principia Mathematica Philosophiae Naturalis in 1687. The second law, ΣF = ma, states that changes in force will cause an object to accelearate and with this equation, one can figure out how much. It can be rewritten into a = ΣF / m, and thus, it can be seen that acceleration…

At (a), the surface is not inclined. When a vehicle moves around a bend or a corner on a flat road, it is moving in circular path. Therefore, it will experience centripetal acceleration and there must be an external force causing centripetal acceleration. As shown in the diagram, the only thing in contact with the car is the road, which is between the tyres of the vehicle and the surface of the road. Therefore, we can know that the frictional force exerted between the tyres and the road directed…

Isaac Newton was one of the most influential scientists of the 17th-century and is now considered one of the most influential scientists of all time. He was born on January 4, 1643 to Hannah Ayscough Newton, in Woolsthorpe, England. Isaac Newton was a physicist and mathematician during the Scientific Revolution. He developed the principles of modern physics that are taught today. By 1666, Newton had developed the theory of gravitation. He had also come up with ideas about the diffraction of…
