Understanding Speed and Velocity

What is the speed of a body that covers 10 meters in 5 seconds?

• 2 meters per second

• 1 meter per second

• 10 meters per second

• 5 meters per second

Which of the following is a scalar quantity?

• Distance

• Velocity

• Displacement

• Acceleration

What is displacement?

• None of the above

• Total distance covered

• Distance in a specific direction

• Rate of change of distance

How is velocity different from speed?

• Velocity is always greater than speed

• Velocity is a scalar quantity

• Velocity is measured in kilometers

• Velocity includes direction

What is the SI unit of speed?

• Miles per hour

• Kilometer per hour

• Feet per second

• Meter per second

Which formula is incorrect?

• Speed = Distance / Time

• Velocity = Displacement / Time

• Speed = Displacement / Time

• Velocity = Distance / Time
