8 ) Use Newton's first law to demonstrate and explain that an object is either at rest or moves at a constant velocity unless acted upon by an external force (e.g., model car on a table remaining at rest until pushed).

[SC2015] PS8 (8) 9 :

9 ) Use Newton's second law to demonstrate and explain how changes in an object's motion depend on the sum of the external forces on the object and the mass of the object (e.g., billiard balls moving when hit with a cue stick).

[SC2015] PS8 (8) 10 :

10 ) Use Newton's third law to design a model to demonstrate and explain the resulting motion of two colliding objects (e.g., two cars bumping into each other, a hammer hitting a nail).*

The third installment of a three-part lesson on Newton's Laws of Motion, this lesson focuses on Newton's 2nd Law and offers review of all three laws. Students will complete graphic organizers to demonstrate their understanding of the three laws of motion. Students will work in tiered groups to prepare a brief presentation to share with the class on a real-life scenario demonstrating Newton's 2nd Law.

This lesson results from a collaboration between the Alabama State Department of Education and ASTA.

Students will conduct an experiment to determine the effect of mass on the distance a toy car will roll. Students will calculate the effect that mass has on the acceleration of the car (the distance the car will roll). Students will also make a prediction of how far the car will roll if more mass is added.

9 ) Use Newton's second law to demonstrate and explain how changes in an object's motion depend on the sum of the external forces on the object and the mass of the object (e.g., billiard balls moving when hit with a cue stick).

In this lesson, students will investigate the relationship between mass, acceleration, and force as described in Newton’s Second Law of Motion.

Students will work in teams to use a wooden car and rubber bands to toss a small mass off of a car. The car, resting on rollers, will be propelled in opposite directions. Students will vary the mass that is being tossed by each car and change the number of rubber bands used to toss the mass.  Students will then measure how far the car rolls in response to the action force generated.

This lesson was created as part of the 2016 NASA STEM Standards of Practice Project, a collaboration between the Alabama State Department of Education and NASA Marshall Space Flight Center.

This learning activity will allow students to observe real-world examples of Newton's Second Law of Motion through a video clip. After the video and class discussion of the video, students will work with a partner to create a list of other real-world examples of Newton's Second Law of Motion.

This activity is a result of the ALEX Resource Development Summit.

The laws of nature are constantly influencing and interacting with our lives. Forces and motion are part of everything we do. How do we know what forces are acting on us or an object for that matter? Can we predict how the laws of motion will affect an object? Is it possible to create an art piece that can prove that these laws of nature exist? In this lesson, students will be able to study forces and motion vocabulary, visualize and describe the three laws of motion, discuss and design an art piece that justifies their knowledge and understanding of forces and motion, and present and interpret their art piece using vocabulary.

Acceleration is a change in velocity. That means acceleration can mean a change in speed or direction. Acceleration can be thought of as an object’s change in velocity over time.

The classroom resource provides a video that will explain Newton's Second Law of Motion. This resource can provide background information for students before they conduct their own demonstrations. There is also a short test that can be used to assess students' understanding.
