Front

What shape do planets orbit the Sun in?

Back

Ellipse

Front

What is Newton's 3rd Law?

Back

For every action, there is an equal but opposite reaction.

Front

Which has more momentum: a car stopped at a red light or a bike moving at 15 mph?

Back

Front

What can be inferred about an object moving in a circle at constant speed?

Back

There is an unbalanced force acting on the object.

Front

What is velocity?

Back

Speed in a specific direction.

Front

What is the formula for Newton's 2nd Law?

Back

F = ma (Force equals mass times acceleration).

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).

Front

What is momentum?

Back

The product of an object's mass and its velocity.

Front

What is the law of universal gravitation?

Back

Every point mass attracts every other point mass with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
