Acceleration

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object over time.

Front

What is the unit of acceleration?

Back

The unit of acceleration is meters per second squared (m/s²).

Front

How is acceleration calculated?

Back

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

Front

What does a positive acceleration indicate?

Back

A positive acceleration indicates that an object's velocity is increasing.

Front

What does a negative acceleration (deceleration) indicate?

Back

A negative acceleration indicates that an object's velocity is decreasing.

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 does a flat line on a distance-time graph represent?

Back

A flat line on a distance-time graph represents that the object is not moving.

Front

What does a steep slope on a distance-time graph indicate?

Back

A steep slope on a distance-time graph indicates that the object is moving quickly.

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

What happens to an object's velocity if it experiences constant acceleration?

Back

If an object experiences constant acceleration, its velocity will change at a constant rate.
