Exploring Force & Motion

SC-4.3.A. uses scientific tools (for example, stopwatch, meter stick, compass) to measure speed, distance, and direction of an object.
SC-4.3.D. knows that objects do not change their motion unless acted upon by an outside force.
SC-4.3.E. understands how friction affects an object in motion.
SC-4.3.F. knows the relationship between the strength of a force and its effect on an object (for example, the greater the force, the greater the change in motion; the more massive the object, the smaller the effect of a given force).
SC-4.3.H. understands how inertia, gravity, friction, mass, and force affect motion.
