What is air resistance?
the force on an object moving through the air that causes it to slow down (also known as drag)
What is a balanced force?
forces acting on an object that are the same size
What is a driving force?
the force that is pushing or pulling something
What is a reaction force?
the support force provided by a solid surface like a floor
What is the definition of streamlined?
shaped to reduce resistance to motion from air or water
What is water resistance?
the force on an object moving through water that causes it to slow down (also known as drag)
