Forces

For this round, we were starting to focusing on Physical Science. Learning physical science is fun and kind of hard too. We focus on different things about Physical science such as Motion and Forces. There’s a lot of trip going on so I miss a lot of stem class.

Forces:

Earth has two forces: Gravity is the force that pulls the object down. The other force is an upward force that may be provided by the ground or other surfaces.

In the picture  above the gravity pulls down with a force of 20 newtons and the table pushes up with a force of 20 newtons. The force of pushing and pulling is with the same newtons so the book just stays still because it balances.

In the  picture above the man with the blue shirt kicks the ball to the left with75 newtons and the man with the yellow shirt kicks the ball with 125 newtons to the right so the ball will go to the right. Because of the force of kicking the ball to the right have greater newtons than the force of kicking the ball to the left.
