Gravitational Force Flashcard

Front

What is the definition of gravitational force?

Back

Gravitational force is the attractive force between two objects with mass, proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Front

True or False: Only large objects like planets have gravity.

Back

False. Any object with mass has gravity.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

How does the mass of an object affect its weight?

Back

The greater an object's mass, the greater its weight, as weight is proportional to mass.

Front

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

Back

The gravitational force decreases as the distance between the objects increases.

Front

What is the formula for calculating gravitational force?

Back

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

Front

What role does Earth's mass play in gravitational force?

Back

Earth's mass is large enough to exert a significant gravitational force on objects near its surface.

Front

What is the gravitational force between you and your desk?

Back

The gravitational force exists but is very small because the masses of you and the desk are tiny compared to Earth's mass.

Front

What is the gravitational constant (G)?

Back

The gravitational constant (G) is a proportionality factor used in the calculation of gravitational force, approximately equal to 6.674 × 10^-11 N(m/kg)^2.

Front

How does gravity affect objects in free fall?

Back

In free fall, all objects accelerate towards the Earth at the same rate due to gravity, regardless of their mass.
