The answer is: any force equal to or greater than the forward momentum of the truck. So many variables enter into calculating a precise measurement of force needed to stop a vehicle - mass of the vehicle, conditions of friction and gravity - is the truck going uphill or downhill, or on a flat surface? Is the road slippery, smooth or rough?

Let's assume that normal conditions apply: a truck weighing 10,000 Kg traveling at an acceleration rate of 5m/s² along a flat smooth surface. Using Newton's second Law of Motion, expressed as a formula F=ma, where F is the Net Force (the sum of all forces acting on an object) in Newtons, m is the mass of the truck, and a is its acceleration rate, assumed here to be 5m/s². By multiplying the mass times acceleration, we see that a whopping 50,000 Newtons would be required to stop this truck. By comparison, the pull of gravity on a person of average weight (72 Kg, or 160 lb) is measured at 686 Newtons. So depending on the type of truck, weather conditions, wind speed, direction of the truck, and effect of gravity and friction (all included in net force, or Newtons) you can see that the actual Force, expressed as N, is a variable.

Any force will do, but the larger the force, the faster will the object stop. The force, of course, has to be applied in the direction opposite to the movement.


Depends on the amount of time we are given to stop the car. Force = mass x acceleration If we are given 1000 000 seconds to stop the car Force = 500kg * 30/1000000 = 0.015N


Cause its a lot bigger and it has greater force if its comin at you!! which hopefully your not in the road!


Any amount of force will do it, no matter how small, as long as it's pointing in the direction opposite to the car's motion. The lighter the force is, the longer you'll have to wait for the car to stop, but any force greater than zero, no matter how small, will eventually do the job.


If you specify what object and what force and in what conditions, it might be possible to answer without the generic answer, "an equal and opposite force".


It depends on a multitude of factors. The truck has more mass than the car, so if they were traveling at the same speed, it would have more momentum, and therefore take more force to stop the truck within in the time it would take to stop the car. But if the car was traveling at a significantly higher rate of speed than the truck, it would take more force to stop the car, within that time period, than it would the truck. It would also be possible to get the car and the truck moving at different speeds, where it would take the same amount of force to stop them at the same time. ================================================== The force required to stop the moving object has nothing to do with its speed. In fact, if you don't mind our being technically precise, there's no such thing as the amount of force required to stop an object. Any force, no matter how large or small, applied opposite to the direction in which the object is moving, will eventually bring the object to rest. Of course, you have to be aware and make allowance for a few laws of Physics: -- Larger forces will get the job done sooner. -- Smaller forces will take more time to do it. -- Whatever the force is, it'll take longer to stop an object with more kinetic energy. -- Whatever the force is, it'll stop an object with less kinetic energy sooner. -- The object's kinetic energy depends on its mass and speed.

The reason that it takes a moving truck a much longer time to stop than it takes a car to stop when the brakes are applied on both is because the truck weighs more. The more mass a vehicle has the longer it will take to stop.

simple a truck stop or hotel if ur not sure stop at a truck stop and camp out with a tent your smart think


Newton's laws of Motion state that Momentum is a product of Mass times velocity. Momentum = Mass x velocity. Therefore, a loaded truck needs a larger force to move it, and once it's moving, it needs more powerful brakes to stop it. So a fully loaded truck will have more momentum and be harder to stop than an empty truck.


According to Newton's second law, the acceleration of a body is directly proportional to the net force and inversely proportional to its mass, a = F/m. Therefore, a less massive truck would be easier to accelerate ("decelerate") to a stop than a more massive truck.


A truck that is more heavy with the same velocity whil the truck is less heavy it will have more momentum!!

It sounds as if you're looking for an equation that will tell you that number. Thereason you haven't found it yet is that there's no such equation.The effect that force has on a moving object is to 'accelerate' it ... change thedirection it's moving, slow it down, speed it up, etc. ... only depending on thedirection of the force compared to the direction of the motion.If you want to stop a moving object, you apply a force to it opposite to the directionit's moving. It makes no difference how large or small the force is. As soon as it startsacting on the object, the object begins to slow down, and you only have to wait for itto stop. Of course, the larger the force is, the sooner the object stops. But in principle,you can stop an asteroid with the force of a feather, if you're willing to wait long enough.There's no such thing as the amount of force 'needed' to stop the object.


The main sign that a truck has a bent frame is when you come to a complete stop, the truck does not stop straight. There is usually some form of vibration as well.
