What is the definition of acceleration?

Back

Acceleration is the rate of change of velocity per unit time.

Front

What is the formula for calculating average velocity?

Back

Average velocity = Total displacement / Total time.

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 the principle of superposition in vector addition?

Back

The principle states that the resultant vector is the vector sum of all individual vectors.
