RP 2-2 Acceleration and Graphs

Front

What does a distance-time graph represent?

Back

Speed

Front

What is the unit of measurement for acceleration?

Back

(m/s²)

Front

What does negative acceleration indicate about an object's motion?

Back

The object is slowing down.

Front

How do you calculate acceleration if a car accelerates from rest to a certain speed in a given time?

Back

Acceleration = (final speed - initial speed) / time.

Front

If a car accelerates from a stop to 70 m/s in 10 seconds, what is its acceleration?

Back

7 m/s²

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is the formula for calculating average speed?

Back

Average speed = total distance / total time.

Front

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

Back

The object is at rest.

Front

What is the significance of the slope of a distance-time graph?

Back

The slope represents the speed of the object.

Front

What is the relationship between acceleration and velocity?

Back

Acceleration is the rate of change of velocity.
