12 Questions
What is the force of attraction between two point masses according to Newton's Law of Universal Gravitation?
Inversely proportional to the square of the distance between them
If the distance between two masses is tripled, how is the force of attraction affected?
It is divided by 9
In the context of bodies (not point masses), what does 'd' represent in Newton's Law of Universal Gravitation?
Distance between their center of masses
Why can't the moon sustain an atmosphere like Earth does?
Its mass is too small
What happens when an object reaches terminal velocity during free fall?
Air resistance equals its weight
What is the acceleration experienced by a body in free fall within a massive body's gravitational field called?
$g$ acceleration
Which factor(s) determines the force of gravity between two masses?
All of the above
What does an inverse square law mean in the context of Newton's Law of Universal Gravitation?
The force of attraction is inversely proportional to the square of the distance between the masses.
What would happen to the force of attraction if the distance between two masses is halved?
The force of attraction would increase by a factor of 4.
How does the mass of an object affect its weight?
Weight is directly proportional to mass.
In relation to terminal velocity, what happens when the force of air resistance becomes equal to an object's weight?
The object stops accelerating and reaches a constant velocity.
How does acceleration due to gravity change as you move further away from a massive body?
Acceleration due to gravity decreases.
Learn about Newton's law of universal gravitation, which states that the force of attraction between two point masses is proportional to the product of their masses and inversely proportional to the square of the distance between them. Explore how the unit of force is Newtons (N) and how the center of gravity is defined. Understand the concept of an inverse square law in relation to gravitational force.
