Exploring Constant Velocity and Motion Maps

What is the main difference between distance and displacement?

• Distance includes direction, while displacement does not.

• Distance is always shorter than displacement.

• Distance measures how far an object has traveled, while displacement measures how far out of place an object is.

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

If an object travels 50 meters east and then 40 meters west, what is its displacement?

• 10 meters east

• 10 meters west

• 50 meters

• 90 meters

Which of the following is a scalar quantity?

• Speed

• Velocity

• Displacement

• Acceleration

How is velocity different from speed?

• Velocity is always greater than speed.

• Velocity includes direction, while speed does not.

• Velocity measures distance, while speed measures displacement.

• Velocity is a scalar quantity, while speed is a vector quantity.

What does it indicate if the dots in a motion diagram are equally spaced?

• The object is accelerating.

• The object is decelerating.

• The object has a constant velocity.

• The object is stationary.

In a dot diagram, what does it mean if the space between the dots increases over time?

• The object is moving in a circular path.

• The object is decelerating.

• The object is accelerating.

• The object is moving at a constant speed.

What do longer velocity vectors in a dot diagram represent?

• Zero velocity

• Greater velocity

• Constant velocity

• Lesser velocity

How can we use dot diagrams to compare the velocities of two objects?

• By comparing the shape of the dots

• By comparing the number of dots

• By comparing the length of the velocity vectors

• By comparing the color of the dots

What is the formula for calculating average speed?

• Average speed = distance / time

• Average speed = velocity / time

• Average speed = acceleration / time

• Average speed = displacement / time
