FLASHCARD QUESTION

Front

What is Circular Motion?

Back

Circular motion is the motion of an object that revolves around a fixed point in a circular path. It can be uniform (constant speed) or non-uniform (changing speed).

2.

FLASHCARD QUESTION

Front

What is Universal Gravitation?

Back

Universal Gravitation is a fundamental force that states every mass attracts every other mass in the universe, with a force proportional to the product of their masses and inversely proportional to the square of the distance between them.

3.

FLASHCARD QUESTION

Front

What is the formula for Newton's Law of Gravitation?

Back

F = Gm₁m₂/r², where F is the gravitational force, G is the gravitational constant, m₁ and m₂ are the masses, and r is the distance between their centers.

4.

FLASHCARD QUESTION

Front

How does distance affect gravitational force?

Back

Gravitational force decreases as the distance between two objects increases. Specifically, it is inversely proportional to the square of the distance.

5.

FLASHCARD QUESTION

Front

What happens to gravitational force if the distance is tripled?

Back

If the distance is tripled, the gravitational force becomes 1/9 of its original value.

6.

FLASHCARD QUESTION

Front

What is the relationship between mass and gravitational force?

Back

Gravitational force is directly proportional to the product of the masses of the two objects. If either mass increases, the gravitational force increases.

7.

FLASHCARD QUESTION

Front

What is the gravitational force between two 1 kg masses 1 meter apart?

Back

Using the formula F = Gm₁m₂/r², where G ≈ 6.674 × 10⁻¹¹ N(m/kg)², the force is approximately 6.674 × 10⁻¹¹ N.
