Sub unit 2 – Balanced and Unbalanced Forces
Objectives: 7.P.1.2 - Explain the effects of balanced and unbalanced forces acting on an object
(including friction, gravity, and magnetics).
Students will understand that…
● Unbalanced forces change an object's motion.
● Balanced forces can have two effects on the motion of objects: the object remains
stationary or it continues the same motion.
● A force must act on an object to change its motion.
Essential Questions:
What is the nature of force?
How do balanced and unbalanced forces affect an object's motion?
What happens to an object's motion if no forces are acting on it?
Vocabulary: balanced force, unbalanced force, magnetic, friction
Objectives:
of an object.
Sub unit 3 – Kinetic and Potential Energy
7.P.2.1 Explain how kinetic and potential energy contribute to the mechanical energy
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 a diagram of a moving object (roller
coaster, pendulum, or cars on ramps as examples).
Students will understand that
- mechanical energy can be either kinetic (energy of motion) or potential (energy of position).
- energy travels and appears in different forms.
- energy can exist as potential or kinetic.
- energy can change forms.
Essential Questions:
- In what ways do kinetic and potential energy contribute to an object's mechanical
energy?
- What is the nature of energy? (refers to law of conservation of energy)
- How does energy change forms?
- What is the relationship between potential and kinetic energy?
- How can you model or diagram energy transformations?
Vocabulary:

Sub unit 4 – Energy Transfer
Objectives: 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.
The student will understand that…
●
●
energy can be transferred between systems through the process of pushing and pulling.
electrical circuits require a complete loop to pass electrical currents.
Essential Questions:
How can energy be transferred between systems?
