Understanding Average and Instantaneous Velocity

What is the main difference between average velocity and instantaneous velocity?

• Average velocity is measured at a specific instant, while instantaneous velocity is over a period of time.

• Average velocity considers total distance and time, while instantaneous velocity is at a specific moment.

• Average velocity is always higher than instantaneous velocity.

• Instantaneous velocity is always zero.

How do you calculate average speed using a position-time graph?

• By calculating the area under the graph.

• By finding the slope of the tangent at a point.

• By dividing the total distance by the total time.

• By measuring the steepest slope on the graph.

What is the slope of a line on a position-time graph indicative of?

• The instantaneous speed at that point.

• The average speed over the entire trip.

• The time taken to travel a certain distance.

• The total distance traveled.

What is a common mistake students make when finding the slope on a position-time graph?

• Using the steepest part of the graph.

• Calculating the area under the curve.

• Dividing the position by the time directly.

• Using the change in Y over the change in X.

How can you estimate the slope on a curved position-time graph?

• By drawing a tangent line and calculating its slope.

• By measuring the curve's height.

• By finding the average of all slopes on the graph.

• By using the total distance and time.
