What is force?

Check out this ball! It’s about to go on a wild ride because of forces! Right now, it's a STILL BALL, just nappin' at the top because no force is touchin' it yet. But look! THE PUSH from that finger gives it a big burst of energy to get it rollin' down the track! As it hits those curvy walls, we see a CHANGING PATH. The walls push back to steer the ball in a new direction! Oh boy, now it’s gettin' bumpy! That’s FRICTION—it’s like invisible hands rubbin' against the ball to slow it down so it doesn't go TOO fast. Then, WHOOSH! GRAVITY takes over, pullin' the ball down the ramp like a giant magnet towards the Earth. Forces are like the hidden engines that make the whole world move! Tiny Concepts.
