Asked by Julie
n important step in science is supporting a theory or idea with data. The questions we ask help determine the type of data we collect.
In the warm up, you reviewed the equation to calculate kinetic energy. What question could you ask about kinetic energy which will include the variables that affect it?

The kinetic energy equation is KE = 1/2 m v^2, so the variables that affect it are mass (m) and velocity (v).
Example research questions:
- How does the kinetic energy of an object depend on its mass and its speed?
- More specific/testable: For a fixed mass, how does kinetic energy change as the object's speed increases?
- Or: For a fixed speed, how does kinetic energy change as the object's mass increases?
You can also state the expected relationship to test: KE is directly proportional to mass and proportional to the square of velocity (doubling mass doubles KE; doubling speed quadruples KE).
