Why does mass have no effect on stopping distance?
QuantumCrash said:Well, if you look at N = mg, and if you noticed m in there, the mass actually influences the N, which influences the F, which changes the aceleration...
From F=ma =>larger mass smaller deceleration.
From F=(mu)N => larger mass, larger Normal force, smaller deceleration.
the m's don't cancel out, if that is what you are implying because that would mean the forces that you are comparing are different.
teclo said:the m's do cancel out, though. the equation reads (mu)*m*g = m*a, solving for the acceleration you get a = mu*g. this came up in physics 1 a few years ago and i was super confused.
According to Newton's second law of motion, the force required to stop an object is directly proportional to its mass and acceleration. However, when it comes to stopping distance, the deceleration of the object is also taken into account. Since an increase in mass also leads to an increase in inertia, it requires a greater force to decelerate the object, resulting in a longer stopping distance.
Yes, there are certain scenarios where mass can have an impact on stopping distance. For example, in a collision between two objects, the object with a greater mass will experience a smaller change in velocity and therefore a shorter stopping distance compared to the lighter object.
Yes, the shape and size of an object can also have an effect on its stopping distance. Objects with larger surface areas experience more air resistance, which can slow down the object and increase its overall stopping distance.
Friction is a force that opposes the motion of an object. When an object is moving, the force of friction acts in the opposite direction, causing the object to slow down and eventually come to a stop. Therefore, the amount of friction between an object and its surroundings can affect its stopping distance.
Yes, there are several other factors that can influence stopping distance, such as the surface condition, the type of surface, and the speed at which the object is moving. For example, a wet or slippery surface will increase the stopping distance, while a rough surface will decrease it. Additionally, a higher speed will require a longer stopping distance compared to a lower speed.
