Introduction to Displacement and the Differences Between Displacement and Distance

The video tutorial introduces the concepts of displacement and distance, emphasizing the differences between them. Displacement is defined as the straight line distance between initial and final points, with direction, while distance lacks direction. The symbol for displacement is delta x, representing the change in position. The tutorial covers the equation for displacement, its dimensions, and provides examples to illustrate these concepts. It also explains different ways to describe direction, including Cartesian, relative, and cardinal directions.

What is displacement defined as?

• The total path length traveled

• The straight line distance between start and end points

• The total distance traveled in any direction

• The distance covered in a circular path

What does the symbol delta x represent in physics?

• Change in time

• Change in distance

• Change in position

• Change in velocity

What is the equation for displacement?

• x initial + x final

• x final - x initial

• x initial - x final

• x final + x initial

Can displacement be negative?

• Yes, it can be negative

• Only if the distance is negative

• No, it is always positive

• It depends on the path taken

Does distance have a direction?

• Only in certain cases

• No, it does not have a direction

• It depends on the reference point

• Yes, it always has a direction

Which of the following is true about displacement and distance?

• Displacement has direction, distance does not

• Distance has direction, displacement does not

• Both have direction

• Both are scalar quantities

What are the default directions in the Cartesian coordinate system?

• Up is negative, down is positive

• Left is positive, right is negative

• Up is positive, down is negative

• North is positive, south is negative

In the example where the initial and final points are the same, what is the displacement?

• Equal to the path length

• Undefined

• Equal to the distance traveled

• Zero

What is the relationship between distance traveled and the magnitude of displacement?

• Distance is always greater than displacement

• Distance is always less than displacement

• Distance is always equal to displacement

• Distance is always greater than or equal to the magnitude of displacement

Which of the following is NOT a way to describe direction?

• Circular directions

• Relative directions

• Cardinal directions

• Cartesian coordinates
