UNIT : Force and Motion FOCUS STANDARDS
7.P.1 Understand motion, the effects of forces on motion and the graphical representations of motion.
- 7.P.1.1 Explain how the motion of an object can be described by its position, direction of motion, and speed with respect to some other object.
- 7.P.1.2 Explain the effects of balanced and unbalanced forces acting on an object (including friction, gravity and magnets).
- 7.P.1.3 Illustrate the motion of an object using a graph to show a change in position over a period of time.
- 7.P.1.4 Interpret distance versus time graphs for constant speed and variable motion.
ESSENTIAL QUESTIONS
- Compare balanced and unbalanced forces?
- How does friction affect the movement of an object?
- What is motion?
- What is reference point? Why is important for describing motion?
- How is speed calculated?
- How do outside forces affect speed?
- What are the basic requirements for a distance versus time graph?
- How can a graph be analyzed for the motion it represents?
- What do we mean by “equal but opposite” reaction?
- What are Newton’s 3 laws of motion?
UNIT Force and Energy FOCUS STANDARDS
7.P.2 Understand forms of energy, energy transfer and transformation and conservation in mechanical systems.
- 7.P.2.1 Explain how kinetic and potential energy contribute to the mechanical energy of an object.
- 7.P.2.2 Explain how energy can be transformed from one form to another (specifically potential energy and kinetic energy) using a model or diagram of a moving object (roller coaster, pendulum, or cars on ramps as examples).
- 7.P.2.3 Recognize that energy can be transferred from one system to another when two objects push or pull on each other over a distance (work) and electrical circuits require a complete loop through which an electrical current can pass
- 7.P.2.4 Explain how simple machines such as inclined planes, pulleys, levers and wheel and axels are used to create mechanical advantage and increase efficiency.
ESSENTIAL QUESTIONS
- What are the different forms of energy? How do the different forms of energy differ?
- How does the position of an object relate to its energy?
- What is work?
- What are some examples of energy transfer?
- What happens to energy once it is transferred to another system?
- What is necessary for you “turn on” and “turn off” an electric bulb?
- How do simple machines make work easier?
- What are some examples of each of the classes of simple machines?
- What is mechanical advantage?
