An 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?

Example research question: "How does an object's kinetic energy depend on its mass and its speed?"
You can make it more specific/testable, e.g.:
- "How does the kinetic energy of a cart change as its mass is increased while its speed is kept constant?"
- "How does the kinetic energy of a moving cart change as its speed is doubled, with mass kept constant?"
Independent variables: mass (m) and speed (v). Dependent variable: kinetic energy (KE = 1/2 mv^2). Controls: friction, measurement method, surface, etc.
