Yes, a moving semi-truck has significantly more kinetic energy than a moving baby buggy due to its greater mass and velocity. Kinetic energy is directly proportional to an object's mass and the square of its velocity, so the larger and faster-moving semi-truck will have much more kinetic energy than the smaller and slower baby buggy.
"Large" is a very indefinite word. A larger truck than a car could be a 2 ton flatbed or a 40 ton semi.
A parked semi truck has no momentum. A moving bicycle does. If both the bike and the truck are moving at the same speed in the same direction, the truck will have more because it has more mass.
More force would be needed to stop a semi truck than a motorcycle. This is because a semi truck is heavier and has more momentum, requiring more force to slow down or stop.
It depends on what kind of truck your driving. It its a van, not more than a day. If you are driving a semi-truck, than you can be on the road for a day or two.
The Toyota would have more acceleration a= F/m if the mass of the of the Semi Truck is greater than the mass of the Toyota.
No. Recent advance in technology do not require idling of a semi.
A semi truck and trailer is 8 feet wide. So, wider than that. Additionally, you'd want to ensure that they enough space to make the turn.
Semi trucks or 18 wheelers
The weight of the truck depends on the size. If you have a semi truck with a trailer it will weigh less, rather than if it had the trailer it would weigh more. If you have a large engine than it will have less space in the interer and less space inside. If you have bunk-beds than that will take more space, and so on. So really it all depends on the brand,( for interer) size, and truck check.
Truck drivers typically drive vehicles larger than cars, such as semi-trucks, tractor-trailers, or delivery trucks. These vehicles are used to transport goods and materials over long distances.
It sounds to me like you're describing a straight truck, rather than a semi-tractor. I'd need to know the model number before I gave you an answer... what you're describing could be either be a single or a tandem axle truck.
