Physics Fundamentals: Distance, Displacement, Velocity, and Acceleration

If a car travels at a speed of 60 km/h for 2 hours, how far does it go?

• 30 km

• 120 km

• 60 km

• 240 km

What is the displacement of a bird that flies 3 km north, then 4 km east?

• 5 km northeast

• 7 km

• 12 km

• 3 km

What is the main difference between speed and velocity?

• Speed is a vector quantity, while velocity is not.

• Velocity can change even if speed is constant.

• Speed has a direction, but velocity does not.

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

A car accelerates from 0 to 60 km/h in 5 seconds. What is its acceleration?

If you walk 400 meters north and then 300 meters south, what is your total displacement?

• 700 meters north

• 100 meters north

• 700 meters

• 100 meters

What is the velocity of a car that travels 150 km west in 3 hours?

• 50 km/h west

• 50 km/h east

• 150 km/h

• 450 km/h west

How do you calculate the average speed of a trip?

• Total distance divided by total time

• Total displacement divided by total time

• Final velocity minus initial velocity

• Initial velocity plus final velocity divided by 2

A runner completes a 400 m track in 50 seconds. What was their average speed?

• 8 m/s

• 400 m/s

• 50 m/s

• 8 km/h

What is the displacement of an object that moves in a circular path and returns to its starting point?

• Equal to the circumference of the circle

• Zero

• Cannot be determined without knowing the radius

• Equal to twice the radius of the circle

If a car decelerates from 100 km/h to 50 km/h in 5 seconds, what is its acceleration?
