Strand 2: Properties and Principles of Force and Motion
2. Forces affect motion
Major Objectives IS Suggested Activities
These samples activities offer ideas and are
not meant to limit teacher or student
Concept A: Forces are classified as either
contact forces (pushes, pulls, friction, buoyancy)
or non-contact forces (gravity, magnetism) that
can be described in terms of direction and
magnitude
Scope and Sequence – Force, Motion, and Work
resourcefulness.
Suggested Assessments
These samples assessments offer ideas and are
not meant to limit teacher or student
resourcefulness
a. Identify and describe the types of forces acting
on an object in motion, at rest, floating/sinking
(i.e., type of force, direction, and amount of
force in Newtons)
T
W
a. Students will use appropriate
technologies to measure and compute the
direction and magnitude of the forces
causing the motions of common
activities. (1.1; 1.3; 1.4; 3.5)
a. Students will accurately measure the
magnitude and direction of forces acting
upon various bodies. They will describe
how those forces result in acceleration.
b. Student will compare the forces acting on an
object by using a spring scale to measure them
to the nearest Newton
Concept B: Every object exerts a gravitational
force on every other object
Scope and Sequence – Force, Motion, and Work
T
b. Students will demonstrate the use of a
spring scale for determining weight and
compare that to determining mass of a
balance scale. (1.1; 1.3; 1.4; 3.5)
b. Students will make accurate
measurements of the weight (in Newtons)
of common objects in the classroom.
They will describe why Newtons are used
in science as opposed to pounds.
a. Recognize that every object exerts a
gravitational force of attraction on every other
object
R
a. Students will research the work of
Newton and his simple gravitational
formula. (1.2; 1.8)
a. Students will accurately describe the
influence of gravitational forces on the
motions of planets around the sun.
b. Recognize that an object’s weight is a measure
of the gravitational force of a planet/moon
acting on that object
R
b. Student will compute weights of known
objects on other planets in the solar
system. (1.1; 1.3; 1.8; 2.3)
b. Students will make accurate calculation
about body weight on various planets in
our solar system. They will compare
these with the planets’ masses.
c. Students will research the work of
Cavendish and discover how he
c. Students will accurately describe the
influence of gravitational forces on the
