WHY IS THE TOPIC IMPORTANT TO
THE SOCIETY: Gravity and friction are two forces that work together to allow life as we know it on earth. They are balanced forces. There is no movement without first overcoming friction, which is why a heavier object falls faster due to gravity than a lighter object. A heavy object is not resisted by air friction, while a very light object is (which causes it to fall more slowly).

3 advantages of friction: 1.)it is becomes difficult to walk on a slippery road due to low friction. When we move on ice it becomes difficult to walk due to low friction of ice. 2.)we can not fix nail in the wood or wall if there is not friction.it is friction which holds the nail. 3.)a horse can not pull a cart unless friction furnishes him a secure foothold

3 disadvantages of friction: 1.)the main disadvantage s of friction is that it produces heat in various parts of machines. In this wat some useful energy is wasted as heat energy. 2.)due to friction we have to exert more power in machines. 3.)due to friction noise also produced in machines
Friction force and what does it state: newton’s law of universal gravitation states that every point mass in the universe attracts every other point mass with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

Example of everyday life when we use friction: Friction makes walking and running possible. If there were no friction ,we would be unable to move our legs on the ground without slipping and falling, just like we would experience when we try to move on a slipping surface, such as ice which offers very little friction underfoot. 3 advantages of gravity: 1. Because of earth's gravity we are able to stay on the top of it and other creatures as well.

2. Because of gravity

    Gravity pulls objects to the ground anywhere on Earth. To begin, the gravitational pull of the Earth is the “attraction” that Earth exerts on an object or the object exerts on Earth. Gravity is a force. It forces things to drop or stay on the ground and not fly up into the air. The gravitational pull can be calculated by the mass of an object, the mass of the Earth, and the distance between the center of the Earth. Next, free fall is when objects are falling towards the ground. Therefore, an object that is in the air is always considered in free fall motion. A plane (when it is flying) is in free fall motion, but not in downward free fall motion. Finally, the less dense an object is, the…

    Friction and Shoe Slide

    Answer: The frictional force did depend on the weight of the shoe. The more mass a shoe had, the large frictional force was required. The more weight a shoe has, the more gravity pulls on the shoe. Because of that, there was a larger normal force, which multiplied by the same coefficient of friction gives a larger frictional force.…

    A World Without Friction

    • 645 Words
    • 2 Pages

    Without friction, many obvious things which we take for granted would not function the way we like. Shoelaces would untie themselves, zippers would always unzip (unless they were upside-down), nails, screws, nuts and bolts would work themselves loose, and driving as we know it would be impossible. Objects would be unable to gain traction on any surface. Therefore, the only way to move without friction would be through force of reaction. One would need to push something to get motion in opposite direction. Then even to stop, one would need to collide with something. In short, one would need some mechanism like rockets have to control motion. A larger problem would be that the threat of meteorites would be multiplied immensely (Goulding). Since there would be no resistance as the meteorite entered Earths atmosphere, even small meteorites would be able to penetrate our atmosphere and cause immense damage (Goulding). The damage a large meteor would cause would be catastrophic.…
