- Q1What is the main difference between speed and velocity?Velocity includes direction.Velocity is always constant.Speed is faster than velocity.Speed measures distance only.30s
- Q2If a car travels 60 kilometers in 1 hour, what is its speed?120 kilometers per hour60 kilometers60 kilometers per hour30 kilometers per hour30s
- Q3Which of the following describes velocity?It does not involve time.It is always the same as speed.It only considers how far something has traveled.It includes both speed and direction.30s
- Q4A bike travels east at a constant speed of 15 meters per second. How can we describe its motion?It travels faster than 15 m/s.It has a velocity of 15 m/s east.It is stationary.It has a speed of 15 m/s only.30s
- Q5If two cars are moving at the same speed, but one is going north and the other is going south, what can we say about their velocities?They have no velocity at all.Their speeds are different.Their velocities are different because they have different directions.Their velocities are the same.30s
- Q6If a runner completes a lap around a track of 400 meters in 50 seconds, what is their average speed?10 meters per second400 meters per second8 meters per second20 meters per second30s
- Q7What unit of measurement is often used to express speed?KilogramsKilometers per hourLitersSeconds30s
- Q8Which of the following statements is true about speed?Speed is always increasing.Speed has both magnitude and direction.Speed is a scalar quantity.Speed is the same as velocity.30s
- Q9If a storm is moving at a velocity of 25 kilometers per hour to the northeast, what does this tell us about the storm?It is stationary.Its speed and direction are specified.Its speed is not measurable.It is moving faster than 25 kilometers per hour.30s
- Q10What happens to the velocity of a car if it changes direction while maintaining the same speed?The car must be speeding up.The speed decreases.The velocity changes because direction has changed.The velocity remains the same.30s
- Q11What is the main difference between speed and velocity?Velocity includes direction.Speed is faster than velocity.Speed cannot be measured.Velocity is just speed without time.30s
- Q12If a car travels 60 miles north in 1 hour, what is its velocity?60 miles per hour60 miles per hour north60 miles north1 hour30s
- Q13Which of the following correctly describes speed?Speed is only measured in kilometers.Speed involves direction and distance.Speed is the same as velocity.Speed is how fast an object is moving.30s
- Q14An athlete runs 100 meters in 10 seconds. What is her speed?10 meters per second10 seconds100 meters per second1 meter per second30s
- Q15Which statement best describes velocity?Velocity only concerns the amount of time.Velocity is the same as distance traveled.Velocity has both speed and direction.Velocity can never be negative.30s
