Distance and Displacement Quiz

What is displacement?

• The total length of a path taken

• The length of a straight line between two points

• The time taken to travel between two points

• The speed of an object

How is distance different from displacement?

• Distance is always shorter than displacement

• Distance includes direction, displacement does not

• Distance is the total path length, displacement is the straight line

• Distance is measured in time, displacement in length

In practical terms, why might distance be more meaningful than displacement?

• It is always shorter

• It follows a straight line

• It represents the actual path taken

• It is easier to calculate

How is velocity different from speed?

• Velocity includes direction, speed does not.

• Speed includes direction, velocity does not.

• Both are the same.

• Velocity is always greater than speed.

Match the following terms with the correct definition.

• object with velocity that doesn't change

• speed

• ratio of distance traveled to time taken

• uniform motion

• speed in a specific direction

• velocity

• total length of path actually taken

• distance

A car travels around a circular track at a constant speed. What can be said about its velocity?

• A. The velocity is constant because the speed is constant.

• B. The velocity changes because the direction changes.

• C. The velocity is zero because the car returns to its starting point.

• D. The velocity is greater than the speed because of the circular path.

Answer explanation

The correct choice is B. Although the car travels at a constant speed, its velocity changes because it is constantly changing direction as it moves around the circular track.

Alan travels 100 km in 5hrs. Find his average speed in km/h

• 5km/hr

• 10km/hr

• 50km/hr

• 20km/hr

Answer explanation

To find average speed, use the formula: speed = distance/time. Here, distance = 100 km and time = 5 hrs. So, average speed = 100 km / 5 hrs = 20 km/hr. Thus, the correct answer is 20 km/hr.

What is the formula to calculate speed?

• Speed = Distance x Time
• Speed = Distance/Time
• Speed = Time/Distance
• Speed = Time x Distance

Isla is running a marathon. How would you find her average speed throughout the entire race?

• Measure the time and distance for the first 5 minutes.

• You would take the entire distance the runner traveled and divide the distance by the total time it took the runner to complete the race.

• Run along side her and eyeball it.

• Multiply the total distance by the total time it took her to complete the race.

Calculate the speed:
A Motorcycle traveled 368 Km in 8 Hours

• 2944 Km/hr
• 4.5 Km/hr
• 46 Km/hr
• 0.02 Km/hr
