Balanced and Unbalanced Forces by  The Physics Classroom Summary Force is the push or pull on an object. But what happens if more than one force acts on an object? The combination of two or more forces at once is called the net force. When two forces are acting in the same direction, the net force is the sum of all of the forces, and the object will move in the direction the forces are pushing. If two forces of different rates are acting in opposite directions, the net force is the difference between the two forces. The object moves in the direction the larger force. If two forces of the same rate act in opposite directions, the net force is zero, and the object will not move. We can show the forces acting on an object with force diagrams. The arrows show the direction and size of the force on an object. A force is considered balanced if there are two forces acting on one object that are the same size, but are facing in opposite directions. In balanced forces, ob...

mpinto0205 Ms. Garcia Science 8 1/11/18 Five years ago, self driving cars may have sounded like something out of a fairytale. However, autonomous cars have started to become a reality. Many companies, such as google, tesla, and more, have started building, testing, and troubleshooting the pros and cons of self-driving cars. Within the next few years, self driving cars may be something you see more often in your daily life. There is a lot of controversy over whether self driving cars are worth the risk. There are many factors involved in self-driving cars, however, if there are flaws in the function, self driving cars are not worth the risk. First, self driving cars are not able to visualize the road like humans can. This means faded lines and pedestrians could be an issue for self driving cars. Autonomous cars may also be easy to hack into, which would lead to many safety concerns. Finally, human drivers are much more flexible and adaptable than self-driving cars. Although self-d...
