Acceleration

Front

What is Acceleration?

Back

A change in Motion.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = (Final Velocity (v_f) - Initial Velocity (v_i)) / Time (t)

Front

If a car's speed increases from 10 m/s to 30 m/s in 5 seconds, what is its acceleration?

Back

4 m/s²

Front

What does a negative acceleration indicate?

Back

It indicates that an object is slowing down.

Front

What is the unit of acceleration in the International System of Units (SI)?

Back

meters per second squared (m/s²)

Front

How does direction affect acceleration?

Back

Acceleration is a vector quantity, meaning it has both magnitude and direction.

Front

If an object is moving in a circle at a constant speed, does it have acceleration?

Back

Yes, because its direction is changing.

Front

What is uniform acceleration?

Back

Acceleration that is constant in both magnitude and direction.

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

A dog runs with an initial speed of 7.5 m/s and slides to a stop in 15 seconds. What is the acceleration?

Back

-0.5 m/s²
