# Science Shorts: “Knowing” Newton by: Chris Ohana

##### Journal ArticleDigital resources are stored online in your NSTA Library.

Newton’s Laws seem simple and familiar. Despite their apparent simplicity, these laws are often misunderstood. In the following lesson, students will become better acquainted with Newton and his laws as they test what happens when a force is applied to an object. They will determine that a force either speeds an object or slows it down. Students will test what happens when a force is applied to an object. They will determine that a force either speeds an object up or slows it down. Students will document the speeding up of a toy car as they apply a constant push. They will then investigate the effects of friction on the car to see that forces can speed something up but they can also slow objects down.

A complete lesson is presented for students in elementary grades to help students understand when a force is applied to an object. Students will learn by doing happens when an object speeds up or slows down. They will also learn how friction influences motion as well. It is all there for the teacher and the materials are very easy to acquire.

This article gives an excellent beginning explanation of Newton's Three Laws of Motion. The it gives two activities to experiment on forces. One activity calls for the students to move a car at a steady speed for five seconds. This would be hard for students to accomplish with consistency in order to control the variable of speed.
