Inertial computing power

1. It depends on how long you stop, as well as the quality and speed of the car. The inertia force formula F = ma, assuming that the mass of the car is 1500kg, the braking speed is 100km / h, the car is fully braked in 1 second, and the acceleration reaches 27.77m/s2, then the inertia force is f = 1500 × 100000 / 3600) = 4.17t. At this time, the braking distance is about 14m (which can't be done by racing car). If the normal emergency braking distance is 40m, the braking time is about 2.9s, and the inertia force F = 1.45t. If calculated according to the crash, assuming that the vehicle head collapse distance is 1m, then the acceleration is 385m / S2, the car's inertial force F = 57.85t, and the human's inertial force 2.9t (assuming the body weight is 75kg) is amazing~~

2. The formula F = ma holds in the inertial reference frame. If in the non inertial reference frame, in order to be consistent with F = ma, the pseudo inertial force

3. Inertia is not proced by any field, but the inherent characteristics of the object itself, so inertia is not force.

4. Inertia is the property of an object to keep its own motion state, which is only related to its own mass. The greater the mass, the greater the inertia, the smaller the mass and the smaller the mass. In Newton's second law, a = f / m, the acceleration is inversely proportional to the mass. The larger the mass is, the smaller the acceleration is, and the less easy it is to change the state of motion. The smaller the mass is, the greater the acceleration is, and the easier it is to change the state of motion
inertia is not a force. In fact, it can be understood as another way to explain acceleration. Do you understand? Give and take.

5. Inertial force means that when an object accelerates, the inertia will make the object tend to maintain its original state of motion. If the object is taken as a reference, it looks as if there is a force in the opposite direction acting on the object, so it is called inertial force. Because the inertial force does not exist, only the force that accelerates the object actually exists, so the inertial force is also called the imaginary force. Its concept is put forward because Newton's law of motion is not applicable in non inertial system. But for the convenience of thinking, it can be assumed that in this non inertial frame, in addition to the force caused by interaction, it is also subject to a force caused by non inertial frame inertial force
for example, when a bus brakes, people on the bus lean forward because of inertia. It seems that people on the bus have a force pushing them forward, which is called inertia force. However, only the brake and the friction on the tire make the bus decelerate. In fact, there is no force to push the passengers forward. This is just the performance of inertia in different reference frames
derivation formula
when there is an acceleration a in the system, the magnitude of inertial force follows the formula: F = - MA (M is the mass of the object)
purpose of inertial force
in the study of the motion of the earth's surface atmosphere and water, the geostrophic deflection force is often used as an inertial force. It is also very useful to study the motion of stars in space science, such as why asteroids are torn when they are close to Jupiter (the interaction of inertial force and gravity makes asteroids split), and why comet tails have a deflection angle when they are close to the sun.

6. Er, I think... If inertia is not a force, there is no right force acting on it, only the left force, it will slow down

because when inertia moves forward, if there is no other force acting on it,
it is equivalent to no force, it should keep a uniform straight line motion

7. If you think something is wrong, you should listen to what the teacher says and don't stick to what you think is right
the above are suggestions. If you don't like it, just take it as if I didn't say it< There is no formula for inertia, which is a property of objects.
1. All objects have inertia
2. Inertia is an inherent property of an object
3. Mass is the only measure of inertia
4. Inertia is an attribute of an object, not a force. Therefore, we can't say "subject to inertia", we can only say "e to inertia" or "with inertia"
when you calculate the problem mentioned above, you don't need any inertial formula at all
1, acceleration a = - UMG / M = - UG = - 10u
initial speed is 100km, acceleration is - 10u, then calculate the sliding distance, very simple, slightly
2, reaction force? You mean the force of the ground on the wheels? friction? What is the relationship between F = - UMG
and power? You think too much
3. The impact force depends on the action time of the car and the wall. The shorter the time, the greater the force. It can be calculated according to the momentum theorem. If time is approaching zero, then the force is infinite.
there is a problem in your understanding of inertia. Go to the network to find out what is inertia.

1. If you want a formula, it is to multiply the friction coefficient u (unitless) by the acceleration of gravity g (n / kg), which will get the acceleration a (M / S ^ 2), then calculate the stop time t = V / A, and then 1 / 2 * V * t. It's the so-called formula you want. It's not a formula at all...
2. The impact on your leg is UMG, backward. U is the friction coefficient, M is the mass fraction, G is the acceleration of gravity

8. When the liquid flow is blocked, the inertia force will proce impact, which will damage the parts.

9. The gravity, hydrostatic pressure and wave load acting on the hull is an unbalanced force system, which will inevitably lead to various motions of the ship, resulting in acceleration and corresponding inertial force
