Just like the Sun and the Moon, stars appear to move towards the west. The reason is that Earth rotates in the opposite direction - towards the east.
It is moving either one way or the other. Linear motion is straight line motion. Either the object is moving toward point A or away from it toward point B.
It is moving either one way or the other. Linear motion is straight line motion. Either the object is moving toward point A or away from it toward point B.
An example of acceleration in the direction of motion is a smooth spherical stone dropped from the roof of a building on a windless day. All the motion is straight down, toward the center of the earth, and so is the acceleration.
Length contraction occurs when an object moves at high speeds, causing it to appear shorter in the direction of its motion. This contraction only happens along the direction of motion, not perpendicular to it.
They make random changes in the direction of their movement.
Linear motion is motion in a straight line, where an object moves along a path without changing direction. Nonlinear motion, on the other hand, involves movement that is not in a straight line, exhibiting changes in direction or speed throughout the motion. Examples of nonlinear motion include circular motion or random motion.
No.. this is impossible. Velocity must have a constant direction and speed to remain constant, it may have a constant speed, but the direction in a circle constantly changes. If it suddenly were to have constant direction, then the motion would go off on a tangent.. making it linear motion, not circular. In circular motion, velocity constantly changes. Always.
Uniform motion refers to motion with constant (including zero) velocity: that is, the same speed and in the same direction. Non-uniform motion can refer to motion in which the speed or direction of motion are not constant throughout the period under consideration.
inertia (an object in motion wants to keep moving in that direction)
By definition, friction is opposite of the direction of motion.
The wavelength will be compressed/shortened.
