Friction is the resistance to motion when two objects rub together. An experiment to compare friction on dry and icy surfaces would include the question….

• Is it faster to sled down an icy hill or a gravel driveway?

• What is friction?

• What makes ice slippery?

• What effect does the height of the hill have on the distance an object travels?

Two students wanted to see who was better at tug of war, what can be said about the force applied by the student who won?

• He applied the greatest force in pushing

• He applied the least force in pushing

• He applied the greatest force in pulling

• He applied the least force in pulling

A students tested the effect of friction on a toy car rolling down a ramp. She constructed the ramp with five lanes and covered each with textured material. What conclusion could the student make based on this experiment?

• The force of friction is greatest on wood

• The force of friction is least on the sandpaper

• The force of friction is least on the tile

• The force of friction is not affected by material
