Accelerated Motion Review

Front

What is average velocity?

Back

Average velocity is the total displacement divided by the total time taken. It is a vector quantity.

Front

How do you calculate displacement?

Back

Displacement is calculated as the final position minus the initial position. It is a vector quantity.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity over time. It can be positive, negative, or zero.

Front

What does a negative acceleration indicate?

Back

Negative acceleration indicates that an object is slowing down or decelerating.

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 direction.

Front

What does a velocity-time graph represent?

Back

A velocity-time graph shows how an object's velocity changes over time. The slope of the graph represents acceleration.

Front

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

Back

A horizontal line indicates constant velocity, meaning there is no acceleration.

Front

What is the significance of the area under a velocity-time graph?

Back

The area under a velocity-time graph represents the displacement of the object.

Front

How do you determine the acceleration from a velocity-time graph?

Back

The acceleration can be determined by calculating the slope of the velocity-time graph.

Front

What is uniform acceleration?

Back

Uniform acceleration occurs when an object's acceleration is constant over time.
