Air Resistance Forces & Motion

Experiment: Take two pieces of paper. Wad one into a tight ball Experiment: Take two pieces of paper. Wad one into a tight ball. Leave the other alone. Predict: When you drop the two pieces of paper which will hit the ground first? Why do you predict this?

Notes Write down the words in yellow. The words in white are discussion points, you may write these down, but are not required.

Air Resistance When an object falls through the air, its surface bumps into air particles. Friction between a moving object and air particles is called air resistance. Air resistance acts against the pull of gravity to slow the moving object. Air resistance depends on an object’s shape and the size of it’s surface.

Air Resistance A folded parachute falls to the ground much faster than an open parachute. The open parachute has a cupped shape and a larger surface, so it rubs against more air particles as it falls. The air resistance slows a skydiver’s fall to the ground. Gravity Air Resistance

Air Resistance Think about our experiment with the pieces of paper, which fell to the ground faster the balled up paper or the flat sheet? Why do you think there was a difference?

Air Resistance Friction and gravity act together on moving objects. Think about a ball rolling down a hill. The force of gravity pulls the ball downward. At the bottom of the hill, the ball keeps rolling, but friction between the ball and the ground slows the ball’s motion. After some time, friction makes the ball stop rolling.
