Acceleration & Graphing

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time. It can be positive (speeding up) or negative (slowing down).

Front

What does a positive acceleration indicate?

Back

A positive acceleration indicates that an object is increasing its speed in the positive direction.

Front

What does a negative acceleration indicate?

Back

A negative acceleration indicates that an object is decreasing its speed or slowing down.

Front

How can you determine if an object is moving in the positive direction?

Back

An object is moving in the positive direction if its velocity is positive.

Front

What does it mean if an object has zero acceleration?

Back

Zero acceleration means that the object is moving at a constant velocity; it is neither speeding up nor slowing down.

Front

What is the significance of a velocity-time graph?

Back

A velocity-time graph shows how the velocity of an object changes over time, allowing us to analyze its motion.

Front

What does the slope of a velocity-time graph represent?

Back

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

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 velocity-time graph indicate?

Back

A downward slope indicates that the object is decelerating or slowing down.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) can be calculated using the formula: a = (final velocity - initial velocity) / time.
