Forces and Motion Round 2

A track begins at 0 meters and has a total distance of 100 meters. Juliet starts at the 10-meter mark while practicing for a race.

After running 45 meters, how far is she from the beginning of the track?

• 10m

• 35m

• 45m

• 55m

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

• Displacement

• Reference Point

• Ending Location

• Distance

An object starts at position 12 on a horizontal line with a reference point of 0. What is the position of the object if it moves 14 units to the left?

• -2

• -26

• 2

• 26

Julie finds a snail on the sidewalk and wants to know whether or not the snail moves throughout the day. She places a single mark on the sidewalk next to the snail.

What will Julie use the mark for initially?

• Determining how fast the snail traveled

• Acting as a standard unit of measure

• Determining the displacement of the snail

• Acting as a reference point for determining motion

Which scenario best describes motion?

• a toy train in position 4 on a number line

• a race track that is 100 meters long

• a ball rolling from point A to point B

• a student living 150 miles from Chicago

Two cars started at the same position and were driven through a city using different streets. The red car traveled north 2 miles, then east 4 miles, and then south 6 miles. The green car traveled south 4 miles and then east 4 miles. Both cars ended at the same location.

Which best compares the motion of the cars?

• he green car had a shorter displacement, but the distance traveled by the cars was equal.

• The red car traveled a shorter distance, but the displacement of the cars was equal.

• The red car had a shorter displacement, but the distance traveled by the cars was equal.

• The green car traveled a shorter distance, but the displacement of the cars was equal.

Sonya is playing a board game, and each space on the board game measures 1 centimeter. She moves her game token 5 spaces up from the start position. Then she moves it 5 spaces to the left. Finally, Sonya moves her token 2 spaces down.

What is the total distance the token moved?

• 2 cm

• 8cm

• 12 m

• 15 cm

Olivia places her pet frog on a line to observe the frog’s motion. The line is divided into sections that measure 1 centimeter each. The frog begins at 0, moves 18 centimeters forward, moves 6 centimeters backward, and then 12 centimeters backward.

What is the frog’s displacement?

• 0

• 16

• 18

• 36

What is necessary to determine the speed of an object?

• the mass and volume of the object

• the shape of the object and the distance it moved

• the mass of the object and the time it took to move

• the distance moved by the object and the time it took to move

What can cause a moving object to increase its speed in a forward direction?

• a force pushing on the object from the opposite direction

• a force that continually acts on the object in the direction the object is moving

• an increase in the mass of the object

• a decrease in the mass of the object
