Physics Ch 02 Const Velocity Motion

Front

What is instantaneous velocity?

Back

Instantaneous velocity is the velocity of an object at a specific moment in time, represented as the slope of the tangent line to the position vs. time graph at that point.

Front

How do you calculate average velocity?

Back

Average velocity is calculated by dividing the total displacement by the total time taken. Formula: Average Velocity = (Final Position - Initial Position) / (Final Time - Initial Time).

Front

What does a horizontal line on a position vs. time graph indicate?

Back

A horizontal line indicates that the object is at rest, meaning its position does not change over time.

Front

What does a straight diagonal line on a position vs. time graph represent?

Back

A straight diagonal line indicates constant velocity, meaning the object is moving at a steady speed in a straight line.

Front

What is the significance of the slope in a position vs. time graph?

Back

The slope of the position vs. time graph represents the velocity of the object. A steeper slope indicates a higher velocity.

Front

What does it mean if two objects' position vs. time graphs intersect?

Back

If two objects' graphs intersect, it means they are at the same position at the same time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is a position vs. time graph?

Back

A position vs. time graph is a visual representation that shows how the position of an object changes over time.

Front

What does a negative slope on a position vs. time graph indicate?

Back

A negative slope indicates that the object is moving in the opposite direction to the positive reference direction.

Front

How can you determine if an object is accelerating from a position vs. time graph?

Back

If the graph is curved, it indicates that the object's velocity is changing, which means the object is accelerating.
