Motion

A linear track begins at 0 m. total distance is 100 m. Julie starts at 10 m. She runs 45 m. What is her distance from the beginning of the track?

• 10 m

• 35 m

• 45 m

• 55 m

All points to the _______ of zero on a horizontal number line are negative.

What is most often given a value of zero to describe an object's position on a straight line?

• displacement

• reference point

• starting point

• ending point

An object starts at position 10 on a horizontal line with a reference point of 0. What is the position of the object if it moves 19 units to the left?

• -9

• 9

• 19

• -19

What does a reference point provide? (check all that apply)

• a position to measure distance

• a way to detect motion

• a place to return to

• a standard for distance variable

• a way to determine speed

Based on the graph, it can be determined that:

• Swimmer 1 and Swimmer 2 were moving in the same direction
• Swimmer 2 is faster than Swimmer 1
• Swimmer 1 and Swimmer 2 were moving in different direction
• Swimmer 1 is faster than Swimmer 2

Which scenario describes motion

• a train that is on elm street

• a driveway that is 100 yards long

• a bowling ball going down the lane

• a student living 20 miles from the school

What is a difference between distance and displacement

• Distance is measured in seconds and displacement is measured in meters

• Distance is always shorter than displacement

• Displacement can be equal to zero if the object ends in the place it began in

• Distance can be equal to infinite when only a small distance has been travelled

An astronaut travels at a speed of 400 m/s for 250 seconds, what is the total distance he traveled?

• 0.625 m

• 100,000 m

• 1.6 m

• 650 m
