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
Concept A: Forces are classified as either contact
forces (pushes, pulls, friction, buoyancy) or noncontact
forces (gravity, magnetism) that can be
described in terms of direction and magnitude
meant to limit teacher or student resourcefulness.
Grade 7
Suggested Assessments
These samples assessments offer ideas and are not
meant to limit teacher or student resourcefulness
Concept B: Every object exerts a gravitational force
on every other object
Grade 7
Concept C: Magnetic forces are related to electrical
forces as different aspects of a single
electromagnetic force
Not assessed at this level
Concept D: Newton’s Laws of Motion explain the
interaction of mass and forces, and are used to
predict changes in motion
Concept E: Perpendicular forces act independently
of each other
Concept F: Simple machines (levers, inclined
planes, wheels and axles, pulleys) affect the forces
applied to an object and/or direction of movement
as work is done
