Alongside NASA astronaut Suni Williams, you are invited to watch and learn from NASA astronauts Mark Vande Hei and Jeff Williams as they demonstrate Newton’s First Law of Motion in microgravity aboard the International Space Station. Astronaut Mark Vande Hei shows how an object at rest tends to stay at rest and an object in motion tends to stay in motion unless acted upon by an outside force. Astronaut Jeff Williams shows what happens to objects inside the International Space Station when they experience a reboost. How does this physics phenomena compare to the motion we experience here on Earth’s surface?
