Speed Calculations #1

What is the formula to calculate distance?

• Distance = Speed + Time

• Distance = Speed - Time

• Distance = Speed x Time

• Distance = Speed / Time

A car travels at a speed of 60 miles/hr for 2 hours. How far does it travel?

• 100 miles

• 110 miles

• 120 miles

• 130 miles

If an object is moving away from a starting point and then stops, what can we say about its motion?

• It was moving at a constant speed away from the start and then came to a stop.

• It was accelerating away from the start and then suddenly stopped.

• It was moving in a circular path and then halted.

• It was moving towards the starting point before stopping.

What does it mean if an object is moving at a constant speed?

• It means the object covers equal distances in equal intervals of time.

• It means the object is accelerating continuously.

• It means the object is moving in a circular path.

• It means the object is at rest.

If a car accelerates from 0 to 60 miles/hr in 5 seconds, what type of motion is this?

• Constant motion

• Uniform motion

• Accelerating motion

• Decelerating motion

What is the unit of distance in the metric system?

• kilometers (km)

• meters (m)

• centimeters (cm)

• millimeters (mm)

What is the unit of speed in the metric system?

• kilometers per hour (km/h)

• meters per second (m/s)

• miles per hour (mph)

• centimeters per second (cm/s)

If a cyclist travels 15 km in 30 minutes, what is their speed in km/hr?

• 20 km/hr

• 25 km/hr

• 30 km/hr

• 35 km/hr

Define scalar quantity.

• A quantity that has both magnitude and direction.

• A quantity that has only magnitude and no direction.

• A quantity that is always positive.

• A quantity that can be represented as a vector.

Define vector quantity.

• A quantity that has only magnitude.

• A quantity that has both magnitude and direction.

• A quantity that has no magnitude or direction.

• A quantity that is always positive.
