Forces (Statics)
By the time you finish all labs, worksheets
and related activities, you should be able to:
1. Describe and give examples of Newton's
1st Law.
Newton's 1st Law: An object at rest or
moving at constant velocity continues its current motion unless acted upon
by an outside agent (force).
2. Given a diagram or a written description
of the forces acting on an object.:
a. draw a force diagram for the object
b. resolve the forces into x and y
components, then find the vector sum of the forces.
c. state whether the velocity of the
object is constant or changing.
3. Given a diagram or description of an
object in equilibrium, including the forces acting on the object, determine
the magnitude and direction of the "missing" force required to keep
the object from accelerating.
4. State Newton's 3rd Law; apply it in
situations in which you are trying to determine all the forces acting on an
object.
All forces come in pairs; paired forces
are equal in magnitude, but opposite in direction. F(A on B) = -F(B on A)
