MS-PS3-5. Construct, use, and present arguments to support the claim that when the kinetic energy of an object changes, energy is transferred to or from the object.
This lesson focuses on these aspects of NGSS Three Dimensional Learning:
Science & Engineering Practices
Disciplinary Core Ideas
Planning and Carrying Out Investigations.
Plan an investigation individually and collaboratively, and in the design: identify independent and dependent variables and controls, what tools are needed to do the gathering, how measurements will be recorded, and how many data are needed to support a claim.
Analyzing and Interpreting Data
Construct and interpret graphical displays of data to identify linear and nonlinear relationships.
PS3.A: Definitions of Energy.
Motion energy is properly called kinetic energy; it is proportional to the mass of the moving object and grows with the square of its speed.
A system of objects may also contain stored (potential) energy, depending on their relative positions.
PS3.B: Conservation of Energy and Energy Transfer. When the motion of an object changes, there is inevitably some other change in energy at the same time.
Energy and Matter.
Energy may take different forms (e.g. energy in fields, thermal energy, energy of motion).
The transfer of energy can be tracked as energy flows through a designed or natural system.
