Universal Gravitation & Uniform Circular Motion

Front

What is the Law of Universal Gravitation?

Back

It states that every object in the universe attracts every other object 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.

Front

If the distance between two objects is doubled, how does the gravitational force change?

Back

The gravitational force becomes one-fourth of its original value.

Front

What is uniform circular motion?

Back

It is the motion of an object traveling at a constant speed in a circular path.

Front

What is the direction of the net force acting on an object in uniform circular motion?

Back

The net force is directed towards the center of the circle.

Front

What is centripetal force?

Back

It is the net force that acts on an object moving in a circular path, directed towards the center of the circle.

Front

How does gravitational force change with distance?

Back

Gravitational force decreases as the distance between two objects increases.

Front

What happens to the gravitational force if the mass of one object is doubled?

Back

The gravitational force between the two objects is also doubled.

Front

What is the formula for gravitational force?

Back

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

Front

What is the relationship between speed and centripetal force in circular motion?

Back

As the speed of an object in circular motion increases, the centripetal force required to keep it in that motion also increases.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.
