Conduct investigations to determine the relative sizes of static and kinetic frictional forces acting between two surfaces.
Conduct investigations to determine what variables (mass, normal force, surface area, surface texture, etc.) influence the size of frictional forces that act between two objects.
Give examples in which static friction is a force of propulsion, initiating the motion of an object. Use force diagrams to illustrate the forces acting on the object during this propulsion process.
Use algebraic relationships that relate the acceleration of an object to its speed and position to make predictions about the motion of objects as they move along straight and circular paths.
Conduct investigations (or demonstrate) that under a variety of conditions when two objects collide they exert equal sized forces on each other.
Describe how the concept of torque is used to explain (and calculate) the rotational effect that forces have when they act on objects.
Conduct investigations to identify the factors that determine the torque produced by a force (Torque = force · lever distance). (For example, what conditions must be met to ensure that the sum of all torques acting on an object is zero, leaving the object in rotational equilibrium?)
Use force diagrams to describe how static friction can prevent an object (that is subject to another force) from moving.
Draw force diagrams to illustrate the action of friction when it acts to slowdown an object. Use an energy argument to describe how friction slows down a moving object.
