Formulating an Investigative Question 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?

its a 5.5 n

glad that

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
