Exploring Motion: Distance, Displacement, Speed, and Velocity

What is the main difference between distance and displacement?

• Distance is measured in meters, while displacement is measured in kilometers.

• Distance is always greater than displacement.

• Distance is the total path traveled, while displacement is the shortest path between two points.

• Distance is a vector quantity, while displacement is a scalar quantity.

How do you calculate the displacement in a right-angle triangle?

• By adding the lengths of the two sides.

• By using the Pythagorean theorem.

• By measuring the angle between the sides.

• By multiplying the lengths of the two sides.

Which of the following is a scalar quantity?

• Acceleration

• Velocity

• Distance

• Displacement

What is the formula for speed?

• Displacement multiplied by time

• Displacement divided by time

• Distance divided by time

• Distance multiplied by time

If you travel 70 meters in 100 seconds, what is your speed?

• 70 meters per second

• 0.07 meters per second

• 7 meters per second

• 0.7 meters per second

What is the main difference between speed and velocity?

• Speed is the rate of change of distance, while velocity is the rate of change of displacement.

• Speed is always greater than velocity.

• Speed includes direction, while velocity does not.

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

How do you calculate average speed?

• Total distance divided by total time

• Total displacement multiplied by total time

• Total distance multiplied by total time

• Total displacement divided by total time

If you travel to a friend's house and back, what is your total displacement?

• The sum of the distances to and from the friend's house

• The distance from the friend's house

• Zero

• The distance to the friend's house

What defines uniform motion?

• Traveling unequal distances in unequal intervals of time

• Traveling equal distances in equal intervals of time in a straight line

• Traveling equal distances in unequal intervals of time

• Traveling unequal distances in equal intervals of time

In non-uniform motion, what is true about the distances traveled in equal intervals of time?

• They are always unequal.

• They are sometimes equal and sometimes unequal.

• They are always zero.

• They are always equal.
