Understanding Motion Graphs

This video tutorial explores the concept of matching motion graphs, focusing on position vs time, velocity vs time, and acceleration vs time graphs. It explains how to interpret slopes to predict velocity and acceleration, discusses the concept of constant acceleration, and examines how to determine if an object is speeding up or slowing down based on the direction of velocity and acceleration. The tutorial also covers continuous motion analysis and provides key takeaways for understanding motion graphs.

What does the slope of a position versus time graph represent?

• Time

• Acceleration

• Velocity

• Distance

If a position versus time graph has a constant negative slope, what can be inferred about the velocity?

• Velocity is constant and negative

• Velocity is zero

• Velocity is constant and positive

• Velocity is increasing

What is the acceleration when the velocity versus time graph has a slope of zero?

• Variable acceleration

• Zero acceleration

• Negative acceleration

• Positive acceleration

In a velocity versus time graph, what does a straight line indicate about acceleration?

• Acceleration is zero

• Acceleration is constant

• Acceleration is decreasing

• Acceleration is increasing

What happens to an object when its velocity is negative and acceleration is positive?

• The object slows down

• The object remains stationary

• The object speeds up

• The object moves in a circle

When does an object speed up according to the direction of acceleration and velocity?

• When acceleration and velocity are in opposite directions

• When acceleration and velocity are in the same direction

• When acceleration is zero

• When velocity is zero

What does a negative velocity indicate about the direction of motion?

• The object is moving upwards

• The object is stationary

• The object is moving left

• The object is moving right

How can you determine if an object is slowing down from a velocity versus time graph?

• The graph is a horizontal line

• The graph is approaching zero

• The graph is moving away from zero

• The graph is a vertical line

What does a flat line at zero on an acceleration versus time graph indicate?

• Variable acceleration

• Constant negative acceleration

• Constant positive acceleration

• Zero acceleration

What is the key to understanding if an object is speeding up or slowing down?

• The magnitude of velocity

• The direction of velocity and acceleration

• The shape of the graph

• The time duration
