Front

What does the variable 'a' represent in physics?

Back

The variable 'a' represents acceleration.

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.

Front

What is the formula for calculating acceleration?

Back

a = (v - v₀) / t
