Chapter 12 Force and Motion

In this chapter students will:
  • Describe examples of force and identify appropriate SI units used.
  • Explain how the motion of an object is affected when balanced and unbalanced forces act on it.
  • Compare and contrast the four kinds of friction.
  • Describe how Earth's gravity and air resistance affect falling objects.
  • Describe the path of a projectile and identify the forces that produce projectile motion.
  • Describe Newton's first law of motion and its relation to inertia.
  • Describe Newton's second law of motion and use it to calculate acceleration, force, and mass values.
  • Relate the mass of an object to its weight.
  • Explain how action and reaction forces are related according to Newton's  third law of motion.
  • Calculate the momentum of an object and describe what happens when momentum is conserved during a collision.
  • Identify the forms of electromagnetic force that can both attract and repel.
  • Identify and describe the universal forces action within the nucleus.
  • Define Newton's law of universal gravitation and describe the factors affecting gravitational force.
  • Describe centripetal force and the type of motion its produces.
