I'm pretty sure that's going to depend on the vehicle's mass. I'm sitting here
performing a gedanken experiment right now, with a house fly and a Mercedes
both hitting the same brick wall.
The supersonic object is hitting air molecules faster than they can get out of the way, so they pile up.
No, a stationary object cannot have a non zero angular acceleration. Angular acceleration is a measure of how an object's angular velocity changes over time, so if an object is not rotating, its angular acceleration is zero.
Following distance is typically measured in seconds. A common rule of thumb is the "3-second rule" where you should leave at least 3 seconds of following distance between your vehicle and the vehicle in front of you. To measure this, pick a stationary object on the side of the road, wait for the vehicle ahead of you to pass it, and then count how many seconds it takes for you to pass the same object.
If the net force acting on a stationary object is zero, then the object will remain at rest and not move. This is in accordance with Newton's First Law of Motion, which states that an object will remain at rest or in constant velocity unless acted upon by an external force.
An object with mass will be accelerated by a gravitational force.If the object were (relatively) stationary, but the gravitational force changed, then the apparent weight would change.
if a truck weighing 5000 lbs traveling 15 mph hits an object , what is the pressure at impact?
Yes. You are always at fault when you hit a stationary object.
Possibly if the boulder was in the roadway, but if it was actually on your property then they are responsbile for hitting a stationary object.
WHAT THE SPEED OF STATIONARY OBJECT?
Impact; collision; crash; accident
true
The stationary object is known as a frame of reference. The earth is a common frame of reference for humans.
In the frame of reference in which the object is stationary, its speed is zero. (Actually, that's kind of a definition of "stationary".)
The supersonic object is hitting air molecules faster than they can get out of the way, so they pile up.
It can be.
A stationary object used to gauge the movement of another object might be called the reference. This could also be termed as the point of reference.
In general, if you hit a stationary object while driving, you are likely to be at fault. As the driver, you are responsible for maintaining control of your vehicle and avoiding collisions with stationary objects. However, there may be exceptions in cases where external factors, such as a sudden medical emergency or a mechanical failure, contributed to the accident.
