In the photo, you see the girl pushes the ball across the table trying to make it into the bin but it stop half way. You might wonder why did it stop half way. It stops because friction causes it to slow down and stop. Friction is a force that happens when 2 sufaces or objects rub aganist each other in oppsite direction. Friction is caused due to small bumps in the objects surface these small bumps are called irregularities. When the irregularities rub against each other the object starts to slow down.
Gravity and Motion
Force is all around us. In this scene you can see that the boy is going to slide down the slide. The force he is going to use to slow the down is friction for e. Two surface that are smooth or rough . The boy and the slide are two different objects. This cause either to side down the slide.- Cesar Martinez
Gravity is a force that pulls objects towards each other. The force of gravity between objects increase with greater mass and decrease with greater distance. Mass is a measure of how much matter is in an object. Weight is the gravitational force exerted on a person or object at the surface of the planet. -Jennifer Maldonado
Ch 10 Section 2
In this photo, this guy is free falling. Free falling is the motion under the force of gravity. He is not falling all the way because air resistance is keeping him up. Air resistane is a force at is caused by air. The force acts in the opposite direction to an object moving through the air. - Maya Valdez
In this slide, the person is pulling on the poles, creating tension on the person's arms.
