A position versus time graph is the principle that the slope of a line on a position time graph is equal to the velocity of an object. These graphs describe motion at the specific feature of objects demonstrated by the shape and the slope of a line on a position versus time graph. The shapes of the position versus time graphs for different types of motion, constant velocity motion and accelerated motion reveal an important principle. The principle is that the slope of the line on the position time graph reveals useful information about the velocity of the object. As a slope goes so goes the velocity. Whatever characteristics the velocity has the slope will exhibit the same. If the velocity has changed in the slope is changed. This principle can be extended to any motion. The physics of motion is the change in position of an object over time. Motion is described in math as displacement, distance, velocity, acceleration, speed and time.

Force is defined as a push or a pole of an object that causes the object to slow down, speed up or stay in one place. Force generally causes an object to move. Friction and gravity are two types of forces that influence how objects move. The force of friction is the force that acts to slow an object down as you ride your bike through town and you encounter sand, your bike will slow down, because sand is a type of friction it is a force working against your legs as they push against the pedals. The force of gravity is pulling objects towards the Earth's center. When a ball is thrown in the air it slows down and falls back to the ground, that is because gravity pulls the ball back towards the earth. Everything on earth is influenced by the force of gravity push and pull forces are opposites meaning they move objects in different directions
