Study Guidelines

Explain Newton’s Second Law of Motion.

Explain why the direction of a force is important.

Identify the relation ship between the forces the objects exert on each other.

Indiana State Grade 7 Science Standards and Benchmarks addressed by this unit:

7.3.17 - Investigate that an unbalanced force, acting on an object, changes it speed or path of motion or both, and know that if the force always acts toward the same center as the object moves, the objects path may curve into an orbit around the center.
