1. Use appropriate tools and techniques to make observations and gather data to determine how forces, including friction, act on an object to change its position over time in relation to a fixed point of reference.
2. Calculate the average speed of a moving object, and distinguish between instantaneous speed and average speed of an object.
3. Create and interpret distance-time graphs for objects moving at constant and nonconstant speeds.
4. Predict the motion of an object given the magnitude and direction of forces acting on it (net force).
5. Investigate and demonstrate how unbalanced forces cause acceleration (change in speed and/or direction of an object’s motion).
6. Assess in writing the relationship between an object’s mass and its inertia when at rest and in motion.
7. Express mathematically how the mass of an object and the force acting on it affect its acceleration.
8. Design and conduct an experiment to determine how gravity and friction (air resistance) affect a falling object.
9. Illustrate how the circular motion of an object is caused by a center-seeking force (centripetal force) resulting in the object’s constant acceleration.
