Understanding Speed-Time Graphs

This video tutorial from Mumu Math and Science explains speed-time graphs, focusing on constant acceleration, constant speed, and constant deceleration. It covers how to calculate acceleration and deceleration rates, and how to determine distance traveled using the area under the graph. The video concludes with a reminder about the importance of kindness.

What is the acceleration from point 0 to A if the speed changes from 0 to 2 m/s in 2 seconds?

• 0.5 m/s²

• 3 m/s²

• 1 m/s²

• 2 m/s²

How can you determine the speed during the constant speed phase from A to B?

• By measuring the time interval

• By looking at the slope of the graph

• By calculating the area under the graph

• By checking the Y-axis value

What is the deceleration from point B to C if the speed decreases from 2 m/s to 0 m/s in 1 second?

• -3 m/s²

• -2 m/s²

• -1 m/s²

• -4 m/s²

How do you calculate the distance traveled from 0 to 2 seconds using the graph?

• By checking the Y-axis value

• By measuring the time interval

• By calculating the area of a triangle

• By finding the slope of the graph

What is the area of the triangle formed from 0 to 2 seconds if the base is 2 and the height is 2?

• 1 m

• 4 m

• 2 m

• 3 m

How do you calculate the distance traveled from A to B using the graph?

• By finding the slope of the graph

• By calculating the area of a rectangle

• By measuring the time interval

• By checking the Y-axis value

What is the area of the rectangle formed from A to B if the base is 5 and the height is 2?

• 12 m

• 10 m

• 8 m

• 5 m

What is the significance of the area under a speed-time graph?

• It represents the time interval

• It represents the distance traveled

• It represents the speed

• It represents the acceleration

What does a horizontal line on a speed-time graph indicate?

• Variable speed

• Constant acceleration

• Constant speed

• Constant deceleration
