Kinetic energy depends on mass AND on speed. For example, if all of these are at rest, they will all have zero kinetic energy.

a 1500lb truck moving at 45 mph
The truck - greater mass.

No, it is kinetic energy, which is the energy of motion.

a matter of mass
The truck - greater mass.
When they're parked they do (which is zero). If a truck and golf cart were both moving at the same non-zero speed, the truck, being more massive, would have the greater kinetic energy.
No. The large truck has more kinetic energy than the car. Mass is a variable in the equation for determining kinetic energy. Kinetic energy equals 1/2 the mass of the object time the speed (really velocity) squared.
If there is fuel in the tank then it has chemical energy in that fuel. If it is moving it has kinetic energy. If it is at the top of a hill then it has gravitational potential energy.
KE = 1/2 mass *velocity squared A direct relationship. More mass, and a truck has more mass, and the more kinetic energy if velocities are held equal.
These include very large things, like planets, and very small ones, like atoms. The heavier a thing is, and the faster it moves, the more kinetic energy it has.
