Kinematics in more than one dimension is also considered in Physics 30. Students should be able to apply concepts of kinematics and dynamics in at least two dimensions. Kinematics and dynamics in three dimen- sions may be developed at the discretion of the teacher, based on the needs and abilities of the students. The main emphasis in section F should be placed on developing an understanding of Newton's laws of motion. Many applications and practical examples of Newton's laws should be used to reinforce the main concepts.
Time is a critical factor in developing understanding.
There should be enough time within lessons for the inconsistencies illustrated by a new experimental result to register. We must provide the time students need for mental restructuring. Hurrying on to the next lesson or the next topic does not allow for sufficient reflection on the implications of the present lesson. Perform activities to collect and analyze data on objects in motion. Make reasonable numerical estimates when solving problems.
