You can't increase a truck's kinetic energy without increasing its speed.

Here's why:

* Kinetic Energy Formula: Kinetic energy (KE) is directly proportional to both mass (m) and the square of velocity (v). The formula is: KE = 1/2 * m * v^2

* Speed is Key: If you keep the mass of the truck constant, the only way to change the kinetic energy is to change the velocity (speed).

What might seem like increasing kinetic energy without speed:

* Increasing Mass: If you add weight to the truck (more cargo, for example), you increase its mass. This *would* increase the kinetic energy at a given speed. However, it's not technically increasing the kinetic energy *without* increasing the speed. The increase in mass directly leads to a higher KE at that same speed.
