Calculate Acceleration Practice

Front

What is acceleration?

Back

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

Front

How is acceleration calculated?

Back

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

Front

What is the unit of acceleration?

Back

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

Front

If an object is accelerating, what does that mean?

Back

It means the object's velocity is changing over time.

Front

What does negative acceleration indicate?

Back

Negative acceleration indicates that an object is slowing down.

Front

Calculate the acceleration of a horse that increases its velocity from 0 m/s to 15 m/s in 10 seconds.

Back

1.5 m/s².

Front

What is the acceleration of a box that slides down an inclined plane and reaches 27 m/s in 3 seconds?

Back

9 m/s².

Front

A motorbike decelerates from 55 m/s to 0 m/s in 5 seconds. What is its deceleration?

Back

-11 m/s².

Front

What does it mean if an object has a constant velocity?

Back

It means the object is not accelerating; its speed and direction remain unchanged.

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).
