What is the speed of impact?
The speed of impact is essentially an effective speed at which the object travels when it affects another object. This can be somewhat simplified for situations in which external forces are ignored or are not present as an absolute value of the sum of the speeds of both objects. When other forces are considered to two objects, such as gravitational force, friction, wind resistance and the similar external forces, then the value of speed at the moment of impact is significantly more complex. The impact speed can be determined for all two objects that come into contact with each other.
In order to easily understand the speed of impact, it is important to first understand the speed in general. Speed is a distance measurement that the object can travel for a given time period and is usually measured in meters per second (m/s). While speed is similar to speeds, two terms cannot be used synonymously, as the speed can also indicate the direction in which the object travels with respect to another reference point. It means that aboutB object with positive speed and object with negative speed in the same system travels in the opposite directions; The speed does not indicate the direction and usually cannot be a negative value.
The speed of the object of the object is basically the speed at which the object travels when it comes into contact with another object. For example, if the rock travels in a vacuum without other power to it and affects another rock that is at rest, then the speed of the rock is the speed of the rock when it hits the rock at rest. If the rock in the previous example traveled at a speed of 100 m/s and hit another rock that directed at 40 m/s, then the impact speed would be 140 m/s from the absolute value of the speed are added to determine the efficient speed at the time of the impact.
In more complicated systems, determining impact speed can be more difficult. This is because other forces often play on the object and over time these forces can affect speed, atthat is traveling. The bullet fired down below the angle from the roof towards the apple sitting on the ground, for example, it would have an initial speed when it is fired and was affected by the gravitational force that would increase its speed by pulling down. The wind resistance to the bullet surface would also change the impact speed as soon as the bullet hit the apple and all these forces would have to be considered to create an accurate model for this type of system.
