Newton's Second Law of Motion | Newton's Laws of Motion | Video for Kids

Have you ever heard someone explain that force equals mass times acceleration? This equation (F = M x A) is Newton's second law of motion. In this Newton's Second Law of Motion video for kids, you and your students will learn about force, mass, and acceleration and how each of these work together.

The "f" in the equation stands for force. Force, as you will learn, can be balanced or unbalanced. If you are playing tug of war, for instance, who will win? The answer depends on the amount of force on each side of the rope. If your side has more mass, then the amount of force goes up, and you will win! However, if your side has less mass, you will lose because the other team will have more force.

Mass is what the "m" in the equation stands for. Mass is essentially the amount of matter something has, which is what everything is made up of. For example, an elephant has far more mass than an insect. But just because something is bigger, it doesn't mean it has more mass. Compare a basketball and a bowling ball. The basketball is bigger than a bowling ball, but the bowling ball has more mass than the basketball. After all, a basketball is filled with air, which definitely does not have a lot of mass!

The "a" stands for acceleration in the force equation. Think of when you press down a gas pedal or the pedal of your bicycle. When you do so, you increase your acceleration. Acceleration means the change in speed or direction. This also applies when you, say, ride a skateboard down a ramp. You accelerate as you roll down the ramp.
