Motion

Mr. Anderson explains motion in AP Physics Essentials Video 38. He uses a tennis ball and meter stick to demonstrate motion, then employs Galileo's inclined plane method for clearer observation. The video covers scalar and vector quantities, graphing displacement, velocity, and acceleration, and emphasizes the importance of frame of reference. The video concludes with designing experiments to test motion.

What method did Mr. Anderson use to better observe the motion of the tennis ball?

• He used a high-speed camera.

• He slowed down the video and used inclined planes.

• He used a telescope.

• He increased the lighting in the room.

Which of the following is a vector quantity?

• Distance

• Time

• Speed

• Displacement

What does the slope of a position vs. time graph represent?

• Time

• Displacement

• Acceleration

• Velocity

How can you determine acceleration from a velocity vs. time graph?

• By finding the area under the curve

• By calculating the slope of the graph

• By measuring the height of the graph

• By counting the number of data points

What happens to the acceleration when the slope of the velocity vs. time graph levels off?

• The velocity decreases

• The object moves backward

• The acceleration becomes zero

• The object stops moving

Why is the frame of reference important in observing motion?

• It alters the color of the object

• It changes the mass of the object

• It affects how motion is perceived

• It determines the speed of the object

Which tool is NOT mentioned as a way to test the motion of an object?

• Motion sensor

• Ticker tape

• Video recording

• Pendulum
