motion along straight line
Answers
yes motion
Explanation:
2. Motion along a straight line
The simplest type of motion is the motion along a straight line.
Two different quantities Distance and Displacement are used to describe the overall motion of an object and to locate its final position with reference to its initial position at a given time.
Distance in physics, is the length of the path (the line or curve) described by an object moving through space. Distance is independent of direction. Thus, such physical quantities that do not require direction for their complete description are called scalars.
When a body moves from one position to another the shortest distance between the initial and final position of the body along with its direction is known as displacement. Displacement has both direction and magnitude for its complete description and hence such physical quantities are called a vectors.
The distance travelled by a moving body cannot be zero but the final displacement of a moving body can be zero.
If a body covers equal distances in equal intervals of time then it is said to be having uniform motion.
If a body covers unequal distances in equal intervals or equal distances in unequal intervals then body is said be having non-uniform motion.
