Constant+Velocity

Constant Velocity Vocab: speed - distance covered in a given time velocity - the total displacement of an object divided by the time in which that displacement occurred distance - how far objects are from one another displacement - the change in position of an object

reference point - observation point or starting point of measurements reference frame - a system for specifying the precise location of objects in space and time

Constant Velocity Examples: an automobile on cruise control the moons orbit around earth the earths orbit around the sun

Velocities: Positive velocities occur when an object moves in a positve (right, up) displacement Negative velocities occur when an object moves in a negative (left, down) displacement

Velocity On Position vs. Time Graph: The velocity on a position vs. time graph is represented in the slope. The slope is known as rise over run (y over x). Velocity is seen as postion over time where position = y and time = x. So on a postion vs. time graph the slope is the velocity.
