Analyzing Motion with Graphs

Mr. Anderson's AP Physics video covers the concepts of position, velocity, and acceleration. He explains how to measure these aspects of motion and discusses the relationship between acceleration and net force. The video uses graphical analysis to illustrate motion, including position vs. time graphs. Practical examples, such as a car and a basketball, demonstrate constant velocity and acceleration. The video emphasizes understanding motion through graphical relationships and mathematical models.

What happens to your position and velocity when you jump out of an airplane?

• Position becomes more negative, velocity decreases

• Position remains constant, velocity decreases

• Position becomes more negative, velocity increases

• Position becomes more positive, velocity decreases

How is velocity calculated from displacement and time?

• Velocity is displacement multiplied by time

• Velocity is displacement divided by time

• Velocity is time divided by displacement

• Velocity is the square of displacement divided by time

What does a straight horizontal line on a position vs. time graph indicate?

• The object is moving in the negative direction

• The object is not moving

• The object is moving with constant velocity

• The object is accelerating

What does a positive slope on a position vs. time graph represent?

• The object is stationary

• The object is moving to the right

• The object is moving to the left

• The object is accelerating

How can you determine the velocity of an object from a position vs. time graph?

• By measuring the distance between two points

• By measuring the area under the curve

• By calculating the slope of the line

• By finding the y-intercept

What does a curved line on a position vs. time graph indicate?

• The object is stationary

• The object is decelerating

• The object is accelerating

• The object is moving with constant velocity

In the video analysis example, what was the acceleration of the basketball?

• -5 m/s²

• 10 m/s²

• -10 m/s²

• 0 m/s²

What is the significance of a straight line on a velocity vs. time graph?

• The object is accelerating

• The object is decelerating

• The object is moving with constant velocity

• The object is stationary

What is the net force acting on an object moving with constant velocity?

• Equal to the gravitational force

• Equal to zero

• Less than zero

• Greater than zero

What tools can be used to analyze motion in a physics lab?

• Stopwatch, ruler, protractor

• Video analysis, ticker tape, motion sensor

• Thermometer, barometer, hygrometer

• Calculator, graph paper, compass
