Front

What happens to an object's speed as the radius of its circular path decreases?

Back

The object's speed decreases.

Front

What is the direction of centripetal acceleration in circular motion?

Back

Centripetal acceleration always points towards the center of the circle.

Front

In uniform circular motion, how do the velocity and acceleration vectors relate to each other?

Back

The velocity vector is tangent to the circle, while the acceleration vector points towards the center.

Front

What is the formula for calculating gravitational force between two objects?

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 of the two objects.

Front

If the gravitational force between two objects is known, how can you find the mass of one object if the mass of the other and the distance are given?

Back

Rearrange the gravitational force formula to solve for the unknown mass.

Front

What is the significance of point 1 in the context of a string breaking while a ball is in motion?

Back

Point 1 indicates the position where the tension in the string is no longer sufficient to keep the ball in its circular path.

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 is the relationship between speed and radius in circular motion?

Back

As the radius decreases, the speed of the object also decreases if the centripetal force remains constant.

Front

What does a diagram showing velocity and acceleration in circular motion illustrate?

Back

It illustrates that velocity is tangent to the circle and acceleration is directed towards the center.

Front

How does the gravitational force change with distance?

Back

The gravitational force decreases with the square of the distance between the two objects.
