Why is it important to understand the motion of an object in terms of its position, speed, direction, and acceleration?

Open Ended

How can you tell if an object is moving?

Multiple Choice

Before Galileo, how did people typically describe the motion of objects?

• In very simple terms such as fast or slow

• By measuring distance and time

• By using meters per second

• By comparing to the speed of light

Multiple Choice

Which of the following best describes how to calculate the speed of an object?

• Divide the distance covered by time taken

• Multiply the distance by the time taken

• Subtract the time from the distance covered

• Add the distance and time together

Multiple Select

Select all legitimate units for describing speed from the following options:

• miles per hour (mi/h)

• kilometers per hour (km/h)

• centimeters per day

• grams per second

Multiple Choice

If a cheetah covers 50 meters in 2 seconds, what is its speed in meters per second?

• 25 m/s

• 100 m/s

• 2 m/s

• 50 m/s

Multiple Select

Which of the following are examples of speeds that can be measured using a speedometer?

• Instantaneous speed

• Average speed

• Maximum speed

• Minimum speed

Multiple Choice

Which of the following best describes instantaneous speed?

• The speed at any instant of time

• The total distance divided by total time

• The highest speed reached during a trip

• The average of all speeds during a trip

Multiple Choice

If a car travels 240 kilometers in 4 hours, what is its average speed?

• 60 km/h

• 80 km/h

• 40 km/h

• 100 km/h

Multiple Choice

What is the formula to calculate the total distance covered if you know the average speed and travel time?

• total distance covered = average speed × travel time

• total distance covered = average speed ÷ travel time

• total distance covered = travel time ÷ average speed

• total distance covered = average speed + travel time

Multiple Choice

If a cheetah runs at a constant speed of 25 m/s, how far will it travel in 10 seconds?

• 250 meters

• 600 meters

• 250 meters

• 60 meters
