Graphing Kinetic Energy
Remember:
Technically, energy is defined as the ability to do work. Less technically, energy is the stuff that
stuff has that allows stuff to do stuff to other stuff. Without this stuff, stuff can‘t do stuff to other
stuff. It is measured in units of Joules.
Kinetic energy (KE) is the energy of motion and is possessed by moving objects. The amount of
kinetic energy a moving object possesses depends on its mass and velocity. KE is calculated
using the formula:
KE = ½mv2
m = mass (kg)
v = velocity (m/s)
ORDER OF OPERATIONS: only square the velocity value; PEMDAS!!
Learning Targets
 Year-Long Target 3: Write valid conclusions using collected/provided data
 Year-Long Target 5: Identify, Breakdown and Implement the Parts of a Scientific
Investigation
 EMM Target 3.3: Calculate kinetic energy using the formula KE = ½mv2
 EMM Target 3.5: Graph data accurately and precisely
Procedure:
 Calculate and record the KE for the variables provided in data table 1
 Graph the calculated KE from table 1 (5 pts)
 The MV is plotted on the x-axis
 Calculate and record the KE for the variables provided in data table 2
 Graph the calculated KE from table 2 on graph 2 (5 pts)
 The MV is plotted on the x-axis
 Calculate the slope of the line on the right side of the paper (units!)
