Motion Speed and Velocity

What is the formula to calculate speed?

• Speed = Distance / Time

• Speed = Distance x Time

• Speed = Distance - Time

• Speed = Distance + Time

A car travels a distance of 200 meters in 20 seconds. What is its speed?

• 20 meters per second

• 5 meters per second

• 15 meters per second

• 10 meters per second

What is the SI unit of speed?

• cm/s

• m/s

• mph

• km/h

How is velocity different from speed?

• Velocity includes direction, while speed does not.

• Velocity is the rate of change of displacement, while speed is the rate of change of distance.

• Velocity is measured in meters per second, while speed is measured in kilometers per hour.

• Velocity is a scalar quantity, while speed is a vector quantity.

A train travels at a speed of 60 km/h for 2 hours. What is the distance it covers?

• 30 km

• 150 km

• 90 km

• 120 km

A person walks 500 meters in 10 minutes. What is their speed?

• 100 meters per minute

• 50 meters per minute

• 250 meters per minute

• 5 meters per minute

What is the formula to calculate velocity?

• Velocity = Mass x Acceleration.

• Velocity = Distance / Time.

• Velocity = Change in position / Change in time

• Velocity = Acceleration x Time.

A car travels 100 meters north in 10 seconds. What is its velocity?

• 10 meters per second south.

• 100 meters per second north.

• 10 meters per second north

• 50 meters per second north.

What is the SI unit of velocity?

• ft/s

• m/s

• cm/s

• km/h

Explain the difference between speed and velocity.

• Speed is measured in meters per second, while velocity is measured in kilometers per hour.

• Speed is scalar, while velocity is a vector.

• Speed and velocity both have direction and magnitude.

• Speed and velocity are the same thing.
