Distance and displacement

• Distance is the total length of the path an object takes. It is a scalar quantity.
• Displacement is the shortest straight-line distance between an objects starting and ending points, considers only "direct" or oerall change in position. It is a vector quantity.
• Motion is a change in position of an object with respect to a fixed point called a reference point over a period of time like walking, running, jumping and etc.
• Reference point is a place or object used for comparison to determine if something is in motion.
• Distance measured is always positive
• Displacement can be positive or negative depending on the reference point.
• There is always distance covered whenever there is a motion.
• Displacement will be zero if the body comes back to its initial position.
• Distance and displacement's unit is always meter
• The total distance covered is equal to the algebraic sum of all the distance travelled in different directions.
• The net displacement is the vector sum of the individual displacement in different directions.
• When an object returns to its original position, it has traveled some distance but no displacement.
• Any quantity that needs to be fully described by identifying its magnitude and direction is referred to as a vector quantity.
• a scalar quantity is a quantity that only has magnitude (or size).
• Displacement Formula is given as S = Sf – Si. Here, S refers to displacement, Sf is the final position and Si is the initial position of the object.
