Air resistance is a frictional force that air pushes against a moving object.  We meet air resistance in our day to day life in many ways. Air Resistance for Kids | What is Air resistance | Physics for Kids Have you ever wondered why things fall slowly through the air, or why it's easier to ride your bicycle downhill than uphill? It's all thanks to a fascinating force called air resistance! In this article, we're going to explore the wonders of air resistance and how it affects objects in motion. So buckle up, young explorers, and let's take a journey into the world of air resistance! What is Air Resistance? Air resistance is a force that pushes against objects as they move through the air. Just like how you feel the wind on your face when you stick your hand out of a moving car, objects also feel the push of air as they travel. This force depends on the shape and size of the object, as well as the speed at which it moves. Air resistance can slow down objects, change...

Gravity for Kids | What is Gravity? | Physics for Kids : What goes up must come down! This is a great lesson for primary graders to learn about the force of gravity. Gravity is a force which tries to pull two objects toward each other. Larger or heavier the object stronger the pull (gravity). Smaller or lighter the object weaker the pull (gravity).
