Friction is a force that two surfaces exert when they are rubbed together.
Did you know that static friction,sliding friction,rolling friction,and Fluid friction are all kinds of frictions
I did not know that.
Weight is the gravitational force exerted on a person or object at the surface of a planet. The equation is Weight=Mass x Acceleration due to gravity.
Gravity is the force by which a planet or body draws objects to its center
Gravity keeps this tipi from floating of the ground.
Gravity keeps us on earth
Mass is the amount of matter in an object. The Si unit of mass is the kilogram. Gravitational force depends on distance between the objects. The farther apart the two objects are the lasses the gravitational force between them.
Free fall- when the only force acting on an object is gravity
Gravity- the force that grounds you to the earth
Air Resistance- a type of fluid friction that acts on an object that is falling through the air the friction acts in the opposite motion of the object
When an object is thrown
A type of Elastic Force that stretches or pulls on molecules in the matter.
A type of Elastic Force that will squeeze or push molecules and matter together
