Maybe you were in class, pondering what in the world the standard S8P3 is all about? Is there a paper I can read for background information? Well, S8P3 is one for the many 8th grade science standards. The standard is about force, mass, and motion. The standard goes in detail about speed, velocity, acceleration, Newton's 3 laws of motion, balanced and unbalanced forces, gravity and friction. As well as the relationship between force, mass, and motion. Force is the first part of the standard. The 3 classifications of force are balanced and unbalanced, friction, and gravity. To start with, balanced and unbalanced are the causes for motion or the stillness of an object. It happens when 2 forces push or pull on the same object. To create a balanced force, the 2 forces acting on one object must be perfectly even. The force being even or balanced will not result in movement. An unbalanced force is when 2 separate forces are acting on one object, but one force is stronger. The next force is friction. Friction is one of the main forces that stop movement. Friction causes objects to slow down and eventually stop moving. It is caused by the rubbing or movement over a rough surface, like sandpaper or even glass. The last and final force is gravity. Which is the force that holds objects …show more content…
Speed is how fast an object is going. Velocity, similar to speed, is how fast an object is going in a particular direction. Even though speed and velocity are both how fast an object is moving, they are still different in some ways. Speed is just how fast, while velocity is the speed and direction. Acceleration is when the speed or velocity of an object changes . An example is if a car was going 50 mph north, then the car went 55 mph east. That is acceleration, because the velocity changed and speed changed. If an object's speed slows down then that is acceleration but to limit confusion it can be called
