Direction, Displacement, Distance

What is the definition of distance?

• The length of the path taken from the starting point to the final point

• The straight-line distance between the starting point and the final point

• The time taken to travel from the starting point to the final point

• The difference between the starting point and the final point

Which of the following best describes displacement?

• The length of the path taken from the starting point to the final point

• The straight-line distance between the starting point and the final point

• The time taken to travel from the starting point to the final point

• The difference between the starting point and the final point

What does direction refer to?

• The length of the path taken from the starting point to the final point

• The straight-line distance between the starting point and the final point

• The time taken to travel from the starting point to the final point

• The angle or orientation of the final point relative to the starting point

If an object travels 10 meters north, then 5 meters south, what is its displacement?

• 5 meters north

• 5 meters south

• 10 meters north

• 10 meters south

How do distance and displacement differ?

• Distance is always positive, while displacement can be positive or negative

• Distance is always negative, while displacement can be positive or negative

• Distance and displacement are always the same value

• Distance and displacement are unrelated

Speed = _______________

• Distance + time

• Distance – time

• Distance x time

• Distance / time

This occurs when an object speeds up, slows down, or changes direction.

• Speed

• Velocity

• Acceleration

• Speed

• Velocity

• Acceleration
