What you need to do:
1. Get a coin. Throw the coin upward. Observe what happens.
2.Slide the coin on the floor. Infer why the coin slows down and stops.
3. Prepare a feather and a coin. Hold the feather and the coin 2 meters above the floor or ground. Observe which one will reach the ground first if you drop the feather and the coin at the same time.
What have you found out:
A.
1. Which object reached the group first?
2. What kind of force causes the coin to fall? Describe it.
3.Why did the coin rolling on the floor slow down and stop?

Answer:
1. The coin reached the ground first.
2. The force that causes the coin to fall is gravity. It is a force that attracts objects towards each other, and is proportional to their masses.
3. The coin rolling on the floor slowed down and stopped due to friction. Friction is a force that opposes motion between two surfaces in contact.
4. The force that opposes the motion of the feather is air resistance. It is a force that acts against the motion of an object through air.
