16/2 (1.3) Graphing of motion: • displacement / time graphs • velocity / time graphs (vertical and horizontal) Use of projectile motion marble/carts, various other projectile systems. Resolving vector components Discuss qualitatively the effects of air resistance. Demonstrate how to determine maximum when vertical displacement = 0 and the angle at which this occurs. Gravity and Motion projectile motion can be analysed quantitatively by treating the horizontal and vertical components of the motion independently This includes applying the relationships Textbook: 2. Motion in a gravitational field 2.2 Projectiles launched horizontally 2.3 Projectiles: Oblique launches EP12: P42 Set 3 23/2 (1.4) Determination of centripetal force and acceleration. Resolution of forces on a banked track (cars, bikes, runners). Understanding of normal force (considering friction) on banked tracks. Discuss effects of friction qualitatively Ferris wheels, rollercoasters, stunt planes, experience of ‘weightlessness’. Need to determine ΣF at various points in vertical circular motion. Also criteria for not falling out of your seat when doing a ‘loop the loop’. Circus acrobats, gymnasts, centrifuges. Assuming that non-uniform CM (vertical). Car over a hump. Gravity and Motion when an object experiences a net of constant magnitude perpendicular to its velocity, it will undergo uniform circular motion, including circular motion on a horizontal plane and around a banked track; and vertical circular motion This includes applying the relationships Newton’s Law of Universal Gravitation is used to explain Kepler’s laws of planetary motion and to describe the motion of planets and satellites, modelled as uniform circular motion This includes deriving and applying the relationship Textbook: 2. Motion in a gravitational field 2.4 Circular motion in a horizontal plane 2.5 Circular motion on banked tracks 2.6 Circular motion in a vertical plane 2.7 Satellite motion EP12: P56 Set 4 Task 1: TEST – Projectile motion and gravity (2.5%)
30/3 (1.9) Easter week Electrons in orbit around the atom. Explaining the concept of charge. Electrons orbiting within an electrostatic field. Electrostatic forces of attraction. Electromagnetism electrostatically charged objects exert a force upon one another; the magnitude of this force can be calculated using Coulomb’s Law This includes applying the relationship Textbook: 4. Electric fields 4.1 The electric field 4.2 Coulomb’s law 4.3 Work done in an electric field 6/4 (1.10) Year 12 Retreat NO YEAR 12 CLASSES! 13/4 (1.11) Define permittivity. Draw simple electric field diagrams. Van der Graaff generator experiments. charges and charged objects produce an electric field in the space that surrounds them; field theory attributes the electrostatic force on a point charge or charged body to the presence of an electric field a positively charged body placed in an electric will experience a force in the direction of the field; the strength of the electric field is defined as the force per unit charge This includes applying the relationship when a charged body moves or is moved from one point to another in an electric field and its potential energy changes, work is done on the charge by the field This includes applying the relationship EP12: P129 Set 9 End of Term 1 – Revise, catch-up, prepare

Analysis of Hubble's data - extrapolation of data gradient to find age of universe. Microwave background radiation. Doppler effect. The Standard Model the expansion of the universe can be explained by Hubble’s law and cosmological concepts, such as red shift and the Big Bang theory the Standard Model is used to describe the evolution of forces and the creation of matter in the Big Bang theory Textbook: 9.
