Purpose To demonstrate that an object continues to move due to inertia. Materials 5 books chair or cart with rollers Procedure Stack the books on the edge of the chair's seat. Push the chair forward then quickly stop the chair. Results The books move forward and fall to the floor. Why? Inertia is a resistance to any change in motion. A moving object remains in motion until some force stops it. The books are moving at the same speed as the chair. They are not attached to the chair. Therefore, when the chair stops, the books continue to move forward.
The card moves so quickly that it translates very little force to the clothespin. The pin falls straight down due to the pull of gravity when the card no longer supports it. If you do not hit the card straight forward with enough force, it pulls the bottom of the pin forward and gravity pulls the top of the pin down, causing the pin to flip before it lands.

Release the marble and observe the cup. Results The cup moves when the marble strikes it. The cup moved an additional distance when the ruler rested on the book. Â < previous page < previous page page_154 page_155 next page > next page > Page 155 Why? Objects at rest have potential energy. The higher the object sits above the ground, the greater is its potential energy. When objects fall or roll down an incline, their potential energy changes into kinetic energyenergy of motion. Increasing the height from which the marble rolled gave it more energy, causing it to strike the cup with more force.
