#1

Which force keeps an object moving along a circular path?

Centripetal force
Explanation

Force directed towards the center of the circle.

#2

What is the direction of the centripetal force acting on an object moving in a circle?

Toward the center of the circle
Explanation

Towards the center of the circle.

#3

What is the direction of the gravitational force between two objects?

Always attractive
Explanation

Always pulling towards each other.

#4

Which scientist is credited with the formulation of the laws of planetary motion?

Johannes Kepler
Explanation

Formulated laws of planetary motion.

#5

What type of motion does a satellite in a circular orbit around the Earth experience?

Uniform circular motion
Explanation

Constant speed in circular path.

#6

What is the formula for centripetal force?

F = mv^2/r
Explanation

Force equals mass times velocity squared divided by radius.

#7

What happens to the centripetal force required to keep an object moving in a circle if the radius of the circle is doubled?

It remains the same
Explanation

Remains unchanged.

#8

What is the centripetal acceleration of an object moving in a circle with a constant speed?

Non-zero and varying
Explanation

Acceleration is present and varies.

#9

Which of the following factors affects the magnitude of gravitational force between two objects?

The mass of both objects and the distance between them
Explanation

Affected by mass and distance.

#10

Which of the following is NOT a requirement for an object to move in uniform circular motion?

A frictionless surface
Explanation

Not needing a frictionless surface.

#11

If the mass of one object is doubled while the mass of the other remains the same, how does the gravitational force between them change?

It is doubled
Explanation

Doubles in magnitude.

#12

What is the gravitational force between two objects proportional to?

The square of the distance between them
Explanation

Proportional to the square of the distance.

#13

What is the gravitational force between two objects inversely proportional to?

The distance between the objects
Explanation

Inversely proportional to distance.

#14

Which law states that every particle in the universe attracts every other particle 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?

Newton's Law of Universal Gravitation
Explanation

Law describing gravitational attraction.

#15

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

It is quadrupled
Explanation

Increases by a factor of four.

#16

What is the unit of gravitational constant G in the equation F = (G * m1 * m2) / r^2?

m^3/(kg * s^2)
Explanation

Cubic meters per kilogram second squared.

#17

What happens to the gravitational force between two objects if the distance between them is tripled?

It becomes nine times smaller
Explanation

Decreases by a factor of nine.
