Circles & Gravity

Front

What is uniform circular motion?

Back

Uniform circular motion is the motion of an object traveling at a constant speed along a circular path.

Front

What direction does the centripetal force act in uniform circular motion?

Back

The centripetal force acts toward the center of the circular path.

Front

What is centripetal acceleration?

Back

Centripetal acceleration is the acceleration directed toward the center of a circular path, which keeps an object moving in that path.

Front

How does the radius of a circular path affect the speed of an object in uniform circular motion?

Back

As the radius decreases, the speed of the object also decreases.

Front

What is the formula for gravitational force between two objects?

Back

The gravitational force (F) between two objects is given by F = G * (m1 * m2) / r^2, where G is the gravitational constant, m1 and m2 are the masses of the objects, and r is the distance between their centers.

Front

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

Back

If the distance is halved, the gravitational force increases by a factor of four.

Front

What is the role of centripetal force in circular motion?

Back

Centripetal force is necessary to keep an object moving in a circular path, preventing it from moving in a straight line due to inertia.

Front

What happens to the centripetal acceleration if the speed of the object increases while the radius remains constant?

Back

If the speed increases while the radius remains constant, the centripetal acceleration increases.

Front

What is the relationship between mass and gravitational force?

Back

The gravitational force is directly proportional to the product of the masses of the two objects.

Front

What is the effect of increasing the mass of one object on the gravitational force between two objects?

Back

Increasing the mass of one object increases the gravitational force between the two objects.
