Understanding Distance, Displacement, Speed, and Velocity

What is the main difference between distance and displacement?

• Both are scalar quantities.

• Both are vector quantities.

• Distance is scalar, while displacement is vector.

• Distance is a vector quantity, while displacement is scalar.

How is distance denoted in the transcript?

• By small m or small n

• By capital D or capital R

• By small d or small r

• By small x or small s

What formula is used to calculate speed?

• Speed = Distance / Time

• Speed = Time x Distance

• Speed = Distance x Time

• Speed = Time / Distance

In the example given, who is moving faster, Peter or Sara?

• It cannot be determined

• Both are moving at the same speed

• Sara

• Peter

What is the key characteristic of velocity that differentiates it from speed?

• Velocity includes direction.

• Velocity is measured in kilometers.

• Velocity is a scalar quantity.

• Velocity is always greater than speed.

How is velocity denoted in the transcript?

• By capital V

• By small v

• By V without any arrow

• By V with an arrow on the head

What is the relationship between speed and distance?

• Speed is the product of distance and time.

• Speed is the ratio of distance to time.

• Speed is the sum of distance and time.

• Speed is the difference between distance and time.

What is the relationship between velocity and displacement?

• Velocity is the product of displacement and time.

• Velocity is the ratio of displacement to time.

• Velocity is the sum of displacement and time.

• Velocity is the difference between displacement and time.

Which of the following is true about speed?

• Speed is a vector quantity.

• Speed includes direction.

• Speed is always constant.

• Speed is a scalar quantity.

Which of the following statements is true about velocity?

• Velocity is a vector quantity.

• Velocity does not include direction.

• Velocity is a scalar quantity.

• Velocity is always constant.
