For example, show how length is defined by time. Explain how these units are interrelated. Review all the base units of the metric system. Explain the meaning of seconds squared in the denominator of the units of acceleration. Explain that converting to base units is a good first step when calculating these quantities. Note that these are some of the seven base units of the metric system. Verify that the students know the SI units in which time, displacement, velocity, and acceleration are expressed. Point out that the variables commonly used to represent these quantities are the first letters of the corresponding term. Review definitions of the terms: time, displacement, velocity, and acceleration. A bar over a symbol, such as a ¯ a ¯, means average.The subscript 0 refers to an initial value sometimes subscript i is instead used to refer to initial value.Acceleration: a, measured in meters per second per second (m/s 2, also called meters per second squared).Velocity: v, measured in meters per second (m/s).Displacement: Δ d, measured in meters (m).Recall that each of these terms has a designated variable and SI unit of measurement as follows: Throughout this chapter we will use the following terms: time, displacement, velocity, and acceleration.

What does a vector arrow represent? Ask them to name some quantities that are vectors and some that are scalars. See how much students remember about vectors. Explain that the capital Greek letter delta always means final minus initial and that the net change may be zero, positive, or negative. Lead students to their topics of interest, such as motor vehicles or sports. Explain that deceleration is not used in physics because acceleration is either positive or negative. Begin a general discussion about acceleration and deceleration.

In addition, the High School Physics Laboratory Manual addresses content in this section in the lab titled: Position and Speed of an Object, as well as the following standards: (B) describe and analyze motion in one dimension using equations with the concepts of distance, displacement, speed, average velocity, instantaneous velocity, and acceleration.(A) generate and interpret graphs and charts describing different types of motion, including the use of real-time technology such as motion detectors or photogates.The student knows and applies the laws governing motion in a variety of situations. The Learning Objectives in this section will help your students master the following standards:
