Front

What law of motion does this picture represent? (Newton's 1st, 2nd, or 3rd law)

Back

Newton's 1st law

Front

What is inertia?

Back

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

Front

What is the formula for calculating momentum?

Back

Momentum = Mass x Velocity

Front

What is Newton's 2nd law of motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is friction?

Back

A force that opposes the motion of an object.

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).
