Understanding Velocity-Time Graphs

What does a positive velocity indicate on a velocity-time graph?

• The object is moving west.

• The object is moving east.

• The object is stationary.

• The object is moving south.

How is a car accelerating to the right represented on a velocity-time graph?

• A horizontal line below the time axis.

• A diagonal line with a positive slope.

• A horizontal line above the time axis.

• A diagonal line with a negative slope.

What does a negative slope on a velocity-time graph indicate?

• The object is stationary.

• The object is speeding up in the negative direction.

• The object is slowing down in the positive direction.

• The object is speeding up in the positive direction.

How can you tell if an object is slowing down on a velocity-time graph?

• The line is vertical.

• The line is horizontal.

• The line approaches the time axis.

• The line moves away from the time axis.

What does a line below the time axis represent on a velocity-time graph?

• The object is stationary.

• The object is moving in the positive direction.

• The object is accelerating.

• The object is moving in the negative direction.

In a multi-stage motion, what does a diagonal line moving towards the time axis indicate?

• The object is speeding up.

• The object is slowing down.

• The object is changing direction.

• The object is stationary.

What does a horizontal line on the time axis indicate about the object's motion?

• The object is stopped.

• The object is decelerating.

• The object is accelerating.

• The object is moving at a constant speed.

What is a common misconception about changing directions on a velocity-time graph?

• A horizontal line indicates a change in direction.

• A line changing slope indicates a change in direction.

• A line crossing the time axis indicates a change in direction.

• A vertical line indicates a change in direction.

What does it mean if a line on a velocity-time graph is horizontal but not on the time axis?

• The object is accelerating.

• The object is moving at a constant velocity.

• The object is stopped.

• The object is decelerating.

How can you identify if an object is speeding up on a velocity-time graph?

• The line is vertical.

• The line is horizontal.

• The line is moving away from the time axis.

• The line is moving towards the time axis.
