Front

What does it mean for an object to accelerate?

Back

When an object changes its speed, direction, or both.

Front

If an object is moving at a constant speed, is it accelerating?

Back

No.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is the difference between speed and velocity?

Back

Speed is scalar (magnitude only), while velocity is vector (magnitude and direction).

Front

Can an object have a constant speed but still be accelerating?

Back

Yes, if it is changing direction (e.g., moving in a circle).
