I think the truck has more inertia because ethe motorcycle seems less dense than the truck.

A truck is heavier, has more mass. So at the same speed, the more massive object has more inertia. A scientific word for inertia is Momentum, defined as mass times speed, and is equal to force times time. So a 1 kilogram mass operated on by a 1 Newton force for 1 second would move at 1 metre per second and would have a momentum of 1 kg-N.
Yes
A moving skateboard has greater momentum than a heavy truck at rest. Momentum is determined by both the mass and velocity of an object, so even though the truck may have more mass, the skateboard's velocity contributes more to its momentum.
This is an example of inertia. Inertia is the tendency of an object to resist changes in its motion. In this case, the skateboard's velocity creates momentum that makes it harder to stop suddenly.
A large truck typically has more inertia than a small car because inertia is directly proportional to an object's mass. The greater mass of the truck means it will resist changes in its state of motion more than the smaller car.
This is an example of inertia, the tendency of an object in motion to stay in motion. As you increase your velocity on a skateboard, your momentum also increases, making it harder to stop because of this inertia.
because it has greater mass
The truck has the most mass, but because it is at rest, the skateboard has the most momentum.
8mm is the size of the truck. From one end to the other.
