Unit 3: TwoDimensional MotionUnit 4: Circular Motion& Universal Law ofGravitationUnit 5: MomentumUnit 6: Work & EnergyThe same basic principles & models govern the motion of all objects, when considering multipledimensions.All physical quantities will behave either as a vector or scalar quantity.At the conclusion of this unit students will be able to:1. Students will be able to apply kinematics and Newton's Laws to objects moving in two dimensions andunderstand how they affect a systems' motion in two dimensions.The same basic principles & models govern the motion of all objects when considering multipledimensions.For an object to move in circular motion with constant velocity, the net force and acceleration must bedirected towards the center of the circle and perpendicular to the circular path.Gravitational force is a universal force of attraction between masses and this force is proportional to theproduct of the masses and inversely proportional to the distance squared.At the conclusion of this unit students will be able to:1. Students will understand that a net external force must be directed toward the center of a circularpath to keep an object traveling in circular motion.2. Students will understand that all objects with mass exert forces on other object with mass andsometimes these forces can cause an object to travel in a circular path.In order to for an object to undergo a change in momentum, an unbalanced and external force(s) mustbe exerted on the object over a period of time.Momentum is conserved in a closed system.At the conclusion of this unit students will be able to:1. Students will understand that momentum is conserved in a closed system.Energy takes many forms; these forms can be grouped into types of energy that are associated with themotion of mass (kinetic energy), and the energy associated with the position of an object in a field(potential energy).Energy is a property of many substances and is associated with heat, light, electricity, mechanicalmotion, sound, nuclei, and the nature of a chemical. Energy is transferred in many ways.The total mass‐energy is conserved in a closed system.At the conclusion of this unit students will be able to:1. Students will understand that energy is conserved within a system.1 week2 weeks2 weeks2 weeks
