Personal Lab 1 Background Motion is such an ingrained part of our daily lives that we rarely pause to contemplate it. We rarely notice the more subtle details of the motions of objects around us. Objects which move horizontally can roll, slide or move through the air.
Liquids can move through pipes that are laid out horizontally.
Winds in stormy weather can blow in a horizontal direction. A train traveling across a flat terrain moves horizontally. A hockey puck swiftly and easily slides in a horizontal path across an ice rink. The conveyor belt carries groceries in a horizontal path toward the clerk in the supermarket. An airliner flies with a horizontal motion when crossing the country at an altitude of 35,000 feet.
