model of constant velocity review 2020

Front

What does a velocity-time graph represent?

Back

A velocity-time graph represents the velocity of an object over time, showing how the object's speed and direction change.

Front

What does it mean if an object is moving with a constant negative velocity?

Back

It means the object is moving in the negative direction at a steady speed, without changing its velocity.

Front

How do you determine the position of an object at a specific time using a position-time graph?

Back

You locate the time on the horizontal axis and find the corresponding position on the vertical axis.

Front

What is the difference between distance and displacement?

Back

Distance is the total path length traveled, while displacement is the straight-line distance from the starting point to the ending point, including direction.

Front

What is the formula for calculating distance traveled?

Back

Distance = Speed × Time.

Front

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

Back

A horizontal line indicates that the object is moving at a constant velocity.

Front

What does a downward slope on a position-time graph indicate?

Back

A downward slope indicates that the object is moving in the negative direction.

Front

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

Back

The slope of a position-time graph represents the velocity of the object.

Front

How can you find the total distance traveled if an object changes direction?

Back

Add the lengths of all segments of the path traveled, regardless of direction.

Front

What does the equation x = (-5)t + 30 represent in motion?

Back

It represents an object moving with a constant negative velocity of -5 units per time unit, starting from a position of 30 units.
