Understanding Speed, Velocity, and Motion Representation

What is the speed of a car that travels 100 meters in 5 seconds?

• 10 meters per second

• 15 meters per second

• 20 meters per second

• 25 meters per second

Which of the following is a unit of speed?

• Meters per second

• Meters per minute

• Meters per hour

• Meters per day

What does average speed represent?

• The speed at the end of a journey

• The speed at the start of a journey

• The highest speed reached during a journey

• The total distance divided by the total time

How is motion represented on a graph?

• By plotting distance against time

• By plotting time against velocity

• By plotting time against speed

• By plotting speed against distance

What does a straight line on a distance-time graph indicate?

• Changing speed

• Acceleration

• Constant speed

• Deceleration

What does the slope of a distance-time graph represent?

• Time

• Distance

• Velocity

• Speed

What does a steeper slope on a distance-time graph indicate?

• Faster speed

• Zero speed

• Constant speed

• Slower speed

What does a zero slope on a distance-time graph mean?

• The object is accelerating

• The object is decelerating

• The object is at rest

• The object is moving at constant speed

How is velocity different from speed?

• Velocity is speed with direction

• Velocity is speed without direction

• Velocity is the average speed

• Velocity is the maximum speed

If a bike travels 30 meters every second to the left, what is its velocity?

• 30 meters per second downwards

• 30 meters per second upwards

• 30 meters per second to the left

• 30 meters per second to the right
