Curriculum Map for Physics: Forces and Friction (H.P.2C.1-3,5)
Instructional Time: 5 90-minute class periods
2014 Standard H.P.3: The student will demonstrate an understanding of how the interactions among objects can be explained and predicted
using the concept of the conservation of energy.
Note: H.P.2C.1 is important to teach at the same time as the H.P.2B objectives. It is listed here and in the H.P.2B document. H.P.2C.4 regarding
Hooke’s Law is discussed in the energy unit with elastic potential energy (H.P.3B).

Focus Question
Activity Description
Expected OutcomeLearning Goal
 Does it require more
force to start an object
in motion or to keep it
in motion?
 Allow students to push
objects or pull objects
with a spring scale to
answer the question.
 Place a penny on a
book. Tilt the book up
until the penny begins
to slide. This illustrates
static and kinetic
friction. Repeat with
sandpaper on the
book.
 Measure forces to
overcome kinetic and
 Identify that static
friction is greater
than kinetic friction
 Contrast static and
kinetic friction
 Describe force
