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 of the objects, and r is the distance between their centers.

Front

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

Back

The gravitational force increases by a factor of 4, since force is inversely proportional to the square of the distance.

Front

What is the gravitational constant (G)?

Back

G = 6.674 × 10^-11 N(m/kg)^2, a constant used in the calculation of gravitational force.

Front

Define gravitational force.

Back

Gravitational force is the attractive force between two masses, proportional to the product of their masses and inversely proportional to the square of the distance between them.

Front

What happens to gravitational force if one mass is doubled?

Back

The gravitational force doubles, as it is directly proportional to the masses involved.

Front

What is the effect of increasing the distance between two objects on gravitational force?

Back

Increasing the distance decreases the gravitational force, as it is inversely proportional to the square of the distance.

Front

Calculate the gravitational force if two 5 kg masses are 2 meters apart.

Back

F = G * (m1 * m2) / r^2 = (6.674 × 10^-11) * (5 * 5) / (2^2) = 8.34 × 10^-11 N.

Front

What is the relationship between mass and gravitational force?

Back

Gravitational force is directly proportional to the product of the masses; as mass increases, gravitational force increases.

Front

Explain the concept of weight in relation to gravitational force.

Back

Weight is the gravitational force acting on an object, calculated as W = m * g, where g is the acceleration due to gravity.

Front

What is the acceleration due to gravity (g) on Earth?

Back

g = 9.81 m/s², the acceleration experienced by an object due to Earth's gravitational pull.
