Static friction occurs between two objects that are not moving relative to each other and prevents the objects from sliding against each other.
Fluid friction occurs between layers within a fluidthat are moving relative to each other.
Measurable evidence that continents are moving relative to each other are the west coast of California and Hawaii.
due to relativistic effects such as time dilation, an observer in either object (an observer in the same inertial frame of reference) will see the other object moving at the speed of lightsee http://math.ucr.edu/home/baez/physics/Relativity/SR/velocity.html for the mathematics behind it
Sorry, Andromeda and earth are moving away from each other, not towards each other.
Yes, the two people on the escalator are in motion relative to each other. However, their relative motion is different from being stationary on the same escalator, as they would perceive each other to be moving at a speed equal to the difference in their individual speeds on the escalator.
If two trains on different tracks are moving at the same speed, they will pass each other. However, if they are moving in opposite directions on parallel tracks, it may appear that they are not passing each other since their relative speed is zero. This is because their velocities relative to each other cancel out.
That is called friction. Friction is the force that resists motion when two surfaces are in contact with each other and moving relative to each other.
Relative motion is the concept that the motion of all objects is relative to other objects. If you are sitting still right now you are not moving relative to the earth, however you are moving relative to sun.
Two surfaces that are not moving past each other are in a state of static friction. This means that there is a force acting between them preventing any relative motion.
Static friction is the type of friction that occurs when objects are not moving relative to each other. It prevents the objects from sliding away from each other when a force is applied.
If two trains are passing each other the relative speed can be found by adding the individual speeds of the two trains. This applies if the trains are passing each other in opposite directions. Should one be passing the other and both be moving in the same direction, the difference of the individual speeds would be the relative speed of the trains.
Static friction occurs between two objects that are not moving relative to each other and prevents the objects from sliding against each other.
The passenger in the rear seat of a car moving at a steady speed is at rest relative to the car itself. This is because the passenger is moving with the same velocity as the car, so they appear to be at rest relative to each other.
The combining of velocities is known as velocity addition or relative velocity. It involves adding or subtracting the velocities of two objects moving relative to each other.
