Front

What is the formula for 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 their centers.

Front

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

Back

The gravitational force is reduced to one-fourth of its original value.

Front

If the mass of one object is doubled, how does it affect the gravitational force between two objects?

Back

The gravitational force becomes twice as strong.

Front

What is the gravitational constant (G)?

Back

G = 6.674 × 10^-11 N(m/kg)^2, it is the proportionality constant in the gravitational force equation.

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.

Front

What is the effect of reducing the distance between two masses to half?

Back

The gravitational force increases by a factor of four.

Front

True or False: Gravity only acts on large objects like planets and stars.

Back

False, gravity acts on all objects with mass.

Front

What is the gravitational force between two 5.00 kg masses separated by 0.750 m?

Back

3.00 x 10^-9 N.

Front

What does it mean when we say gravity is a universal force?

Back

It means that gravity acts between all objects with mass, regardless of their size or location.

Front

How does the gravitational force change if both masses are doubled?

Back

The gravitational force becomes four times stronger.
