Topic 2.2: Displacement and velocity in one dimension (vector quantities)

Objective(s):

Students should be able to (a) define displacement and calculate velocity, and (b) explain the difference between scalar and vector quantities.

Students should understand the special case of motion with constant acceleration, so they can write down
expressions for velocity and position as functions of time, and identify or sketch graphs of these quantities.

Students should be able to (a) explain the relationship between velocity and acceleration, and (b) perform graphical analysis of acceleration.

Students should be able to use the equations to solve problems involving one-dimensional motion with constant acceleration. (both in the horizontal plane and vertical plane)

Topic 2.4: Kinematic equations

Objectives:

Students should be able to (a) explain the kinematic equations of constant acceleration and (b) apply them to physical situations.

Students should understand the general relationships among position, velocity, and acceleration for the motion of a particle along a straight line, so that given a graph of one of the kinematic quantities, position, velocity, or acceleration, as a function of time, they can recognize in what time intervals the other two are positive, negative, or zero, and can identify or sketch a graph of each as a function of time.

Students should be able to use kinematic equations to analyze free-fall.

Students should be able to use the equations to solve problems involving one-dimensional motion with constant acceleration. (both in the horizontal plane and vertical plane)
