Physics Uncovered on Instagram: "Newton’s cradle, with its row of suspended balls, shows how energy and motion transfer from one object to another. When you lift and release one ball, it strikes the others, sending its energy through the line and causing the ball on the opposite end to swing outward. This effect demonstrates the conservation of energy and how momentum moves through connected objects."

Robert Herjavec on Instagram: "Most people don’t fail because they can’t do it. They fail because they pause too long. Just taking consistent steps makes a huge difference."
