What is the definition of position in physics?

• The speed of an object
• The measure of where an object is at a particular time
• The change in position of an object
• The total distance traveled by an object

What is the term for motion in which the position changes the same amount in each time interval?

• Nonuniform motion
• Uniform motion
• Random motion
• Accelerated motion

Starting from one shore, you row a boat across a narrow river to the other shore. The river is 34.0 m wide. As you row, the river current moves your boat down the river a distance of 45.0 m. What is the resultant displacement of your boat?

Starting from one shore, you row a boat across a narrow river to the other shore. The river is 101.0 m wide. As you row, the river current moves your boat down the river a distance of 30.3 m. What is the resultant displacement of your boat?

Your friend rows a canoe across a river 44.0 m wide. Using the GPS on her phone, she determines that her total displacement is 66.0 m. How far down the river did the current move her canoe?

Your friend rows a canoe across a river 22.0 m wide. Using the GPS on her phone, she determines that her total displacement is 88.0 m. How far down the river did the current move her canoe?

You time an ant’s movement as it walks along a meter stick. You record the following data: {(0.0 s, 0.00 m), (1.0 s, 0.08 m), (2.0 s, 0.16 m)}. Determine the ant’s velocity from the slope of the position vs. time graph.

You time an ant’s movement as it walks along a meter stick. You record the following data: {(0.0 s, 0.00 m), (1.0 s, 0.16 m), (2.0 s, 0.32 m)}. Determine the ant’s velocity from the slope of the position vs. time graph.

An object travels 30.0 meters per second and travels 250. meters, how much time has passed since you stopped the stopwatch?

An object travels 50.0 meters per second and travels 150. meters, how much time has passed since you stopped the stopwatch?
