Friction: a force that two surfaces exert on each other when they rub against each other. For example, this young is really cold. Your hands come in contact and move against each other, they produce friction. She is rubbing her hands together to create heat.
I have a large surface area
Static Friction: Is when force is applied to a non-moving object Sliding Friction: Is when 2 solid surfaces go across each other. Rolling Friction: when a solid object rolls over a surface Fluid Friction: A solid object goes through a fluid
Projectile Motion and Elastic Forces
Gravity is the force that pulls objects towards each other. Sir Issac Newton realized that gravity acts everywhere in the universe. The Universal Law of Gravitation states that a force of gravity acts between all objects in the universe. you are not only attracted to the earth but other objects are attracted to you as well. the amount of matter is measured in mass in the SI units this is kilograms. weight is the gravitational force that is exerted on a person or object that pulls you to the surface. Weight is = mass x the accerleration due to garavity, weight is measured in Newtons.
Why does an oak leaf flutter slowly to the ground, while an acorn drops straight down? A type of fluid called air resistance acts on objects falling through the air. Air resistance is an upward force ecerted on falling objects. A leaf falls more slowly than an acorn because the leaf has a larger surface area.
I dont have a large surface area so i fall faster then Mr. Corgie
Projectile motion is an object being thrown or already thrown. Elastic Forces are pieces of matter considered elastic if it returns to its original shape after being squeezed or stretched.
