Cheetah Motion and Displacement Concepts

The video tutorial by Walter explains how to create and analyze velocity vs time and position vs time graphs based on a scenario involving a cheetah's movement. The tutorial covers the steps to plot these graphs, interpret the data, and understand the concepts of acceleration, constant speed, and deceleration. The video concludes with a summary of the graphs and encourages students to apply these concepts.

What is the initial speed of the cheetah at the start of the scenario?

• 0 m/s

• 2 m/s

• 6 m/s

• 4 m/s

How long does it take for the cheetah to reach a speed of 4 m/s?

• 9 seconds

• 3 seconds

• 5 seconds

• 7 seconds

What happens to the cheetah's velocity after it maintains a constant speed for 4 seconds?

• It accelerates further

• It comes to a stop

• It maintains the same speed

• It reverses direction

What is the displacement of the cheetah during the first acceleration phase?

• 15 meters

• 25 meters

• 10 meters

• 20 meters

How is the displacement calculated for a segment where the cheetah is accelerating?

• By multiplying speed and time

• By finding the area under the velocity-time graph

• By dividing the total distance by time

• By adding initial and final velocities

What is the displacement when the cheetah runs at a constant speed of 6 m/s for 7 seconds?

• 36 meters

• 48 meters

• 42 meters

• 54 meters

What is the total displacement when the cheetah decelerates to a stop in 3 seconds?

• 15 meters

• 6 meters

• 9 meters

• 12 meters

What is the significance of the area under the velocity-time graph?

• It represents the time

• It represents the displacement

• It represents the acceleration

• It represents the speed

How does the position versus time graph change when the cheetah accelerates?

• It remains unchanged

• It becomes a vertical line

• It becomes a steeper curve

• It becomes a horizontal line

What is the final step in creating the position versus time graph?

• Calculating the average speed

• Connecting the points with lines

• Reversing the direction of the graph

• Calculating the total time
