A 4-page worksheet
that covers kinetic energy calculations (KE=1/2MV2)
through a set of 7 word problems
provides a summary of kinetic energy (KE)
, including its definition, how KE can change depending on an object’s mass and velocity, and the KE equation (KE=1/2mv2). The summary also includes the proper formula triangle for KE
and describes how to use it to solve for the 3 different variables: KE, M, and V. Finally, the summary lists the 4 elements of a correct solution
, including (1) the correct formula, (2) correct rough work, (3) correct answer rounded to the proper significant figures, and (4) correct units.
feature 7 introductory word problems
that require students to solve for each of the 3 variables.
feature a full color-coded answer key
that can be used by the teacher alone, displayed to students on a screen/interactive white board, or handed out to students who have completed the document.
- Review of kinetic energy, including types of motion
- Review of the KE equation (KE = 1/2mv2)
- Use of a formula triangle to solve for each variable (KE, M, and V)
