Unit Test: Motion

Front

What is speed?

Back

Speed is the distance traveled per unit of time, calculated as Speed = Distance/Time.

Front

What does a velocity-time graph represent?

Back

A velocity-time graph shows how the velocity of an object changes over time.

Front

What does it mean if an object is slowing down on a velocity-time graph?

Back

If an object is slowing down, the slope of the velocity-time graph is negative, indicating a decrease in velocity.

Front

How do you calculate total distance traveled?

Back

Total distance traveled is the sum of all distances covered, regardless of direction.

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.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit of time.

Front

What does a flat line on a distance-time graph indicate?

Back

A flat line indicates that the object is not moving; its distance remains constant over time.

Front

How can you determine if an object is moving at a constant velocity?

Back

An object is moving at a constant velocity if the velocity-time graph is a horizontal line.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What does it mean if the velocity of an object is negative?

Back

A negative velocity indicates that the object is moving in the opposite direction to the defined positive direction.
