### Linear Motion

Linear motion is motion in a straight line. It is the most basic of all motions. Uninterrupted objects will continue to move in a straight line indefinitely. Under every day circumstances gravity and friction conspire to bring objects to rest.

Linear motion is measured in two parts. Speed, and direction. Together these make up the velocity.

Linear motion, is not often used as a starting point for mechanisms. Click on the links below to find how to convert linear motion to other motion types.

Can you give me 10 examples of objects that use linear motion. PLEASE!!! I have already got a car, apple falling from a tree, lift/elevator and a toy train, can you give me something else. It has to have some mechanisms in it. Can you help as soon as possible
