Motion Concepts

What is the formula to calculate speed?

• Speed = Time / Distance

• Speed = Distance * Time

• Speed = Time - Distance

• Speed = Distance / Time

Define velocity and provide its units of measurement.

• Velocity is measured in meters per second (m/s).

• Velocity is measured in kilometers per hour (km/h).

• Velocity is measured in degrees Celsius (°C).

• Velocity is measured in liters per minute (L/min).

If an object travels 50 meters in 10 seconds, what is its speed?

• 5 meters per second

• 10 meters per second

• 7 meters per second

• 3 meters per second

Explain the difference between distance and displacement.

• Distance is scalar, whereas displacement is a vector quantity.

• Distance is a physical quantity, whereas displacement is a mathematical concept.

• Distance is measured in meters, whereas displacement is measured in kilometers.

• Distance is a vector, whereas displacement is a scalar quantity.

A car travels at a speed of 60 km/h. How long will it take to travel 120 km?

• 45 minutes

• 1.5 hours

• 3 hours

• 2 hours

What is the SI unit of time?

• meter

• second (s)

• gram

• minute

How is average speed calculated?

• Average speed = Total distance x Total time

• Average speed = Total distance / Total time

• Average speed = Total distance - Total time

• Average speed = Total time / Total distance

If an object moves 8 meters in 2 seconds, what is its velocity?

• 4 m/s

• 2 m/s

• 10 m/s

• 6 m/s

What is the relationship between distance, speed, and time?

• Distance / Speed = Time

• Distance = Speed + Time

• Distance = Speed * Time

• Distance - Speed = Time

A train travels at a speed of 100 km/h for 3 hours. How far does it travel?

• 250 km

• 150 km

• 400 km

• 300 km
