Front

What is acceleration?

Back

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

Front

What is the formula for acceleration?

Back

a = (ev - sv) / t, where 'ev' is the ending velocity, 'sv' is the starting velocity, and 't' is the time taken.

Front

How is acceleration calculated?

Back

Acceleration is calculated by dividing the change in velocity by the time taken for the change to occur.

Front

What does a positive acceleration indicate?

Back

A positive acceleration indicates that an object is speeding up.

Front

What does a negative acceleration indicate?

Back

A negative acceleration (deceleration) indicates that an object is slowing down.

Front

If a ball rolls from 5 m/s to 15 m/s in 2 seconds, what is its acceleration?

Back

5 m/s²

Front

If an object's velocity changes from 10 m/s to 30 m/s in 5 seconds, what is its acceleration?

Back

4 m/s²

Front

If a train slows down from 30 m/s to 10 m/s in 10 seconds, what is its acceleration?

Back

-2 m/s²

Front

What is the unit of acceleration?

Back

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

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.
