What is the primary difference between speed and velocity?

• Speed is a scalar, while velocity is not.

• Velocity includes direction, speed does not.

• Speed is faster than velocity.

• Velocity can only be measured in cars.

Which of the following is a vector quantity?

• Distance

• Time

• Speed

• Velocity

If you travel 180 miles in 3 hours, what is your average speed?

• 540 miles per hour

• 3 miles per hour

• 180 miles per hour

• 60 miles per hour

What is instantaneous speed?

• The average speed over a journey.

• The total distance divided by total time.

• The speed at a specific point in time.

• The highest speed reached during travel.

Which statement is true about speed?

• It includes direction.

• It cannot be measured in miles per hour.

• It is a vector quantity.

• It is the distance traveled over time.

What does it mean if a car is traveling at 60 miles per hour north?

• This is the car's direction only.

• This is the car's acceleration.

• This is the car's velocity.

• This is the car's speed.

What is the significance of direction in defining velocity?

• Direction is not important for velocity.

• Direction combined with speed defines velocity.

• Velocity is only about speed, not direction.

• Velocity is the same regardless of direction.

What does acceleration refer to?

• The rate of change of direction only.

• The rate of change of velocity, which can include changes in speed or direction.

• The rate of change of speed only.

• The rate of change of velocity only.

How can acceleration occur?

• Only by speeding up.

• Only by slowing down.

• By changing speed or direction.

• Only by maintaining constant speed.
