Newton's First Law of Motion

Observe what happens to the motion of the penny. Which of Newton's Laws does this represent?

• Newton's 1st Law, inertia

• Newton's 2nd Law, Force = m x a

• Newton's 3rd Law, action/reaction

Answer explanation

Newton's 1st Law of inertia causes the penny to stay in place/drop straight down and enables me to catch it right where my elbow used to be.
