multiix said:Two spaceships are traveling relative to Earth (stationary). One spaceship is going to the right at 0.8c the other is going to the left at 0.8c. Could you say their relative speed to one another is .8c+.8c? I'm thinking not since you can't possible go faster then the speed of light, doesn't matter what the frame of reference is.
Please Help me with the Theory behind this
Relative speed refers to the velocity of an object in relation to another object. It is the speed at which one object is moving with respect to another object.
Relative speed is calculated by finding the difference between the velocities of the two objects. This can be done by subtracting the speed of one object from the speed of the other object.
Relative speed plays a crucial role in collisions as it determines the impact force and damage caused. The higher the relative speed between two objects, the greater the damage will be upon impact.
Relative size refers to the size of an object in relation to another object. It is the comparison of the size of one object to the size of another object.
Relative size can be calculated by finding the ratio of the sizes of two objects. This can be done by dividing the size of one object by the size of the other object and expressing it as a fraction or percentage.
