Back

Front

What is the term for the force that opposes motion between two surfaces in contact?

Back

Front

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

Back

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the difference between speed and velocity?

Back

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