Inertia

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…

Have you ever seen someone dive off the diving board? Do you enjoy swimming? Well now I’m going to give you a little more information on swimming and what the physics of it is. You will see swimming in a whole different way. Gravity is always affecting you while swimming. Even you don’t think it is. Force of attraction by which terrestrial bodies fall toward the center of the earth. Newton’s first law of motion has a part to do with swimming. An object in motion stays in motion until another…

argument. Objects do not travel up and down in a straight line; instead, objects move, when falling, in a like arch shape. Consequently, modern readers conclude that Aristotle’s argument must be incorrect. Not until Newton formed his Principle of Inertia in the 1600’s, did people know that “an object in motion tends to stay in motion, unless acted on by an outside force” and therefore that objects fell in arch shapes—not straight up and down. In other words, prior to the 1600’s people believed…

The sport known as badminton has its origins in ancient civilisations in Europe and Asia. The ancient game was known as battledore (bat or paddle). Shuttlecock was probably originated more than 2000 years ago in the 1600s, where it was just two people hitting a shuttlecock back and forth without it hitting the ground. In 1934, the International Badminton Federation was formed, with the initial countries, which included England, Wales, Ireland, Scotland, Denmark, Holland, Canada, New Zealand…

Although there were many scientists and mathematicians in the 16th century, Sir Isaac Newton and James Gregory stood out the most. Isaac created the three laws of motion, and James had important results on infinite series expansions of various trigonometric functions. Some other scientists from the 17th century were Galileo Galilei, Willebrord Snell, and Nicholas Cabeus. Some other mathematicians from the 17th century were Ole Roemer, John Collins, and Robert Hooke. These are only some…

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…

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,…

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…
