This experiment demonstrates inertia, a property of matter.
Things Required:
Index card
A coin of any size
Drinking glass
Directions:
Lie the index card over the mouth of the glass. Place the coin on top of the card. Its position is to be centred over the mouth of the glass.
Snap the card with your finger.
This Is What Happens:
The card quickly moves forward and the coin drops into the glass.
Science Behind It:
The stationary card and coin are said to be at rest. They remain motionless because of their inertia. Inertia is the tendency of material not to change its motion or state of rest. When the card is snapped, it slips under the stationary coin. Gravity pulls the coin down into the glass.
