What is Erosion
200
The word that describes that an object or part of an object changes position
What is movement
200
The force caused when two objects rub against each other.
What is friction
200
A force caused by different or similar poles

What is momentum
400
Give an example when humans want to increase friction for safety reasons.
Many answers. Some will include: wearing boots in winter, salting the roads to melt the ice.
400
Objects must contain what two metals in order to be attracted to a magnet
