Front

Why do we say a car accelerates when it goes around a corner at 20 mph?

Back

Because it is changing direction.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Change in velocity) / (Time interval)

Front

What does acceleration measure?

Back

The rate of change of velocity.

Front

Can an object accelerate if its speed remains constant?

Back

Yes, if it changes 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

What is negative acceleration also known as?

Back

Deceleration.

Front

How does gravity affect acceleration?

Back

Objects in free fall accelerate at 9.81 m/s² due to gravity.
