Motion: Speed

What is the formula to calculate speed?

• Speed = Distance + Time

• Speed = Time / Distance

• Speed = Distance x Time

• Speed = Distance / Time

If a car travels 100 miles in 2 hours, what is its speed?

• 25 miles per hour

• 75 miles per hour

• 150 miles per hour

• 50 miles per hour

How is speed different from velocity?

• Speed has direction.

• Velocity is a scalar quantity.

• Speed is the magnitude of velocity.

• Speed is the same as velocity.

What is the SI unit of speed?

• km/h

• miles/h

• m/s

• cm/s

Explain the concept of average speed.

• Average speed = Total distance x Total time

• Average speed = Total time / Total distance

• Average speed = Total distance - Total time

• Average speed = Total distance / Total time

What is the speed of an object if it covers 50 meters in 10 seconds?

• 10 meters per second

• 7 meters per second

• 5 meters per second

• 3 meters per second

How can you calculate the speed of an object if you know the distance it traveled and the time taken?

• Speed = Distance / Time

• Speed = Distance - Time

• Speed = Time / Distance

• Speed = Distance x Time

What is the speed of a car that travels 200 km in 4 hours?

• 50 km/h

• 60 km/h

• 40 km/h

• 30 km/h

What is the difference between speed and acceleration?

• Speed is always positive, while acceleration can be negative.

• Speed is the distance covered per unit time, while acceleration is the change in velocity per unit time.

• Speed is a scalar quantity, while acceleration is a vector quantity.

• Speed is the rate of change of position, while acceleration is the rate of change of speed.

If a train travels at a speed of 60 km/h for 3 hours, how far does it travel?

• 180 km

• 90 km

• 120 km

• 200 km
