Unit: Newton’s Third Law

 Grade: 9-12 Content Area: Science Course Name: Physics Description of Unit: In this unit, students will explore Newton’s Third Law of Motion and Momentum concepts. The relationship between impulse and momentum will also be made by the students. Approximate Time Needed: 7-10 days

Benchmarks:        5.1 I can use vectors and free-body diagrams to describe force, position, velocity and acceleration of objects in two-dimensional space. (9P.2.2.1.1)

5.2 I can recognize that inertia is the property of an object that causes it to resist changes in motion. (9.2.2.2.1)

5.3 I can apply Newton’s three laws of motion to calculate and analyze the effect of forces and momentum on motion. (9P.2.2.1.2)

5.4 I can explain and calculate the acceleration of an object subjected to a set of forces in one dimension (F=ma). (9.2.2.2.2)

5.5 I can demonstrate that whenever one object exerts force on another, a force equal in magnitude and opposite in direction is exerted by the second object back on the first object. (9.2.2.2.3)

5.6 I can use conservation of momentum and conservation of energy to analyze an elastic collision of two solid objects in one-dimensional motion. (9P.2.2.2.3)

Essential Questions:         How will a change in the force affect the momentum of an object?

How does the interaction of two objects change the state of motion for each?
