Position and Motion

reference point

• the process of changing position.

• an object’s distance and direction from a reference point

• the starting point you choose to describe the location, or position, of an object.

• the speed and the direction of a moving object.

position

• a measure of the distance an object travels in a given amount of time.

• an object’s distance and direction from a reference point.

• a push or a pull on an object

• a measure of the change in velocity during a period of time.

motion

• the process of changing position

• a push or a pull on an object

• contact force that resists the sliding motion of two surfaces that are touching

• a quantity that has both magnitude and direction

displacement

• the combination of all the forces acting on an object.

• a simple model to understand what will happen to an object due to a force

• a measure of the distance an object travels in a given amount of time

• the difference between the initial, or starting, position and the final position.

speed

• a push or a pull on an object

• a measure of the distance an object travels in a given amount of time

• a quantity that has both magnitude and direction.

• the forces two objects apply to each other

velocity

• when colliding objects bounce off each other

• the speed and the direction of a moving object.

• a force that one object applies to another object without touching it

• a region of space that has a physical quantity (such as a force) at every point.
