# Make A Map – Newton’s 3 Laws of Motion

On December 14th, we used BrainPOP again to make a mind map about Newton’s 3 laws of motion.

Newton’s first law is: “An object in motion will stay in motion, and an object at rest will stay at rest unless an unbalanced force acts on it.” So if something keeps moving and suddenly stops, it will still go forward until an unbalanced force acts on it. The unbalanced force is invisible so you can’t see it.

Newton’s second law is: “An object that has an unbalanced force acting on it will accelerate in the direction of that force.” So when you sit when you are on the sofa at home, 2 forces act on you. Gravity and an upward force pushing against gravity. If you slide down a slide, gravity wins because they are not cancelling each other out.

Newton’s third law is:”Forces always occur in equal and opposite pairs.” Which means if you push a door open, it comes back at you with an equal force. The door moved because friction is in between. The door is on hinges, which causes less friction.

I learned a lot about Newton’s 3 laws of motion. I enjoyed creating the mind map.
