The characteristic that will be affected by increasing the speed of an object from 30 meters per second to 40 meters per second is **kinetic energy**.
Kinetic energy (KE) is given by the formula:
\[
KE = \frac{1}{2} mv^2
\]
where \( m \) is the mass of the object and \( v \) is its velocity. As the speed (velocity) of the object increases, the kinetic energy increases as the square of the velocity. In this case, since the speed is changing, the kinetic energy will change accordingly.
So, the answer is:
• kinetic energy
