Why is displacement a vector quantity and not a scalar quantity?

A scalar quantity is one which can be described by its magnitude only and does not require a direction. Speed is a scalar quantity. A vector quantity, on the other hand, needs both magnitude and direction for its complete description. Velocity is a vector quantity.


Displacement is the difference between the initial position and the final position of a body. Displacement is a vector quantity and not a scalar quantity because it can be only...

A scalar quantity is one which can be described by its magnitude only and does not require a direction. Speed is a scalar quantity. A vector quantity, on the other hand, needs both magnitude and direction for its complete description. Velocity is a vector quantity.


Displacement is the difference between the initial position and the final position of a body. Displacement is a vector quantity and not a scalar quantity because it can be only described by using both magnitude as well as direction. Distance, on the other hand, is a scalar quantity, since we need to know only about the path taken. In comparison, the path does not matter in the case of displacement. 


When describing the displacement of a body, we usually ask something like, "a body started from origin and reached the coordinates (4,5) in 10 seconds. Determine its displacement." 


Hope this helps.

What is the meaning of "juggling fiends" in Macbeth?

Macbeth is beginning to realize that the three witches have been deceiving him since he first encountered them. Like jugglers, they have kept changing their forecasts in order create confusion. This is particularly apparent when the Second Apparition they raise in Act IV,   Scene 1 tells him that no man of woman born can overcome him in hand-to-hand battle--and then Macbeth finds himself confronted by the one man he has been avoiding out of a...

This is particularly apparent when the Second Apparition they raise in Act IV,   Scene 1 tells him that no man of woman born can overcome him in hand-to-hand battle--and then Macbeth finds himself confronted by the one man he has been avoiding out of a sense of guilt, and that man tells him: Despair thy charm.

Discuss movements that were inspired by the Civil Rights Movement and list one success for each group.

African-Americans contributed in a very big way during World War II. These contributions were demonstrated at home and on the battlefield. After the war, African-Americans properly felt it was time for them to achieve equality with white Americans. During the 1950's, the modern Civil Rights Movement was born and it had a number of successes (integration of the military and Brown vs. Board of Education as examples.) This success inspired other activists to demand change... African-Americans contributed in a very big way during World War II. These contributions were demonstrated at home and on the battlefield.

What are some tensions between men and women in Shakespeare's Julius Caesar?

Julius Caesar is a largely male-driven play. Calpurnia and Portia are the two main female characters, and they are both wives of major characters. Calpurnia is Julius Caesar’s wife. She makes public appearances with him, but there may be some awkwardness between them because of her inability to have children. He publicly tells Antony to touch Calpurnia to cure her of barrenness when he runs the Lupercal, a “holy race” and fertility festival. Calpurnia has... Julius Caesar is a largely male-driven play.
