Final Review

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What is weight?

Back

The gravitational force exerted on an object, calculated as mass times the acceleration due to gravity (Weight = mass × g).

Front

What happens to objects in free fall?

Back

They experience gravitational acceleration and pull on Earth while Earth pulls on them.

Front

What is static friction?

Back

The force that prevents surfaces in contact from sliding past each other.

Front

What is gravity?

Back

The attractive force between two objects that depends on their masses and the distance between them.

Front

What is the difference between static friction and sliding friction?

Back

Static friction prevents motion, while sliding friction acts on moving objects.

Front

What is centripetal force?

Back

The force that keeps an object moving in a circular path, directed towards the center of the circle.

Front

What is momentum?

Back

The product of an object's mass and its velocity (Momentum = mass × velocity).

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 gravitational force?

Back

F = G * (m1 * m2) / r^2, where G is the gravitational constant, m1 and m2 are the masses, and r is the distance between their centers.
