Motion Graphs

Which of the following graphs shows that an object is moving with an increasing positive velocity?

• 
• 
• 
• 

Which of the following best describes the motion of the object between 0 s and 5 s?

• The object's velocity is decreasing.

• The object is moving in the opposite direction relative to its point of origin.

• The object is moving with a constant speed.

• The object's velocity is equal to zero.

What is the velocity of the object in the first 5 s?

• 5 m/s

• 1 m/s

• 2.5 m/s

• 3 m/s

Which of the following best describes the motion of the object between 5 s and 10 s?

• The object is moving with a constant speed.

• The object is moving towards East direction.

• The object is moving with a decreasing speed.

• The object is at rest.

Considering the graph, what is the average velocity of the object?

• 2.5 m/s

• 12.5 m/s

• 1 m/s

• 0 m/s

An LRT train travels along a straight track from one station to another. The graph shows how the velocity of the train varies with time over the whole journey.

At what time interval did the train start decelerating?

• between 0 s to 2 s

• between 2 s to 6 s

• between 12 s to 16 s

• the train did not decelerate

What is the acceleration of the train during the first two seconds of the journey?

• 10 m/s²

• 20 m/s²

• 30 m/s²

• 40 m/s²

Given the graph, determine the displacement between the two train stations? (Note: Use calculator answer.)

• 520 m

• 500 m

• 420 m

• 320 m

Which of the following best describes the motion of the train between 2 s and 12 s time interval?

• The train is at rest.

• The train is moving a decreasing velocity.

• The train is moving with a constant velocity.

• The train is moving with a constant acceleration.

If the train covered a displacement of 520 m, what is the velocity of the train? (Note: Use the calculator answer.)

• 42.5 m/s

• 38.5 m/s

• 32.5 m/s

• 28.5 m/s
