Adventures in Motion and Force
Dave and Mia were playing tag in the park when Dave tripped over a stone and fell. 'Why did I fall down?' Dave wondered aloud. Suddenly, a superhero named FlashForce appeared. 'That's because of gravity,' he explained. 'It's a force that pulls everything towards the Earth.' Later, Dave and Mia found an old box they wanted to move. Despite their best efforts, the box wouldn't budge. FlashForce explained that it was because of another force called friction, which slows down motion. After a day of play and unexpected lessons in physics, Dave and Mia realized that forces are at work all around them.
