S,V,A Review

Front

What does a positive acceleration indicate about an object's motion?

Back

The object is increasing its speed over 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 acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time.

Front

What does a velocity-time graph represent?

Back

It shows how the velocity of an object changes over time.

Front

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

Back

The object is moving at a constant velocity.

Front

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

Back

The object is experiencing negative acceleration (slowing down).

Front

What does an upward slope on a velocity-time graph indicate?

Back

The object is experiencing positive acceleration (speeding up).

Front

If an object is not moving, what is its velocity?

Back

The velocity is zero.

Front

How can you determine which runner completed a race in the least amount of time?

Back

By comparing their speeds or the time taken to complete the distance.

Front

What does it mean for an object to speed up during an interval?

Back

It means the object's velocity is increasing during that time.
