Newton's Law of Universal Gravitation

Front

What does Newton's Law of Universal Gravitation state?

Back

Every point mass attracts every other point mass in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Front

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

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 the centers of the two masses.

Front

What is the gravitational constant (G)?

Back

The gravitational constant (G) is approximately 6.674 × 10^-11 N(m/kg)^2 and is used in the calculation of gravitational force.

Front

How does mass affect gravitational force according to Newton's Law?

Back

The gravitational force increases as the mass of either object increases.

Front

How does distance affect gravitational force according to Newton's Law?

Back

The gravitational force decreases as the distance between the centers of two masses increases.

Front

What is 'apparent weight'?

Back

Apparent weight is the weight that a person feels, which can differ from actual weight due to acceleration or other forces acting on the body.

Front

What is the relationship between gravitational force and distance?

Back

Gravitational force is inversely proportional to the square of the distance between the centers of two masses.

Front

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

Back

If the distance is halved, the gravitational force increases by a factor of four.

Front

What is the significance of scientific notation in physics?

Back

Scientific notation is used to express very large or very small numbers in a compact form, making calculations and comparisons easier.

Front

What is the effect of increasing the mass of one object on the gravitational pull between two objects?

Back

Increasing the mass of one object increases the gravitational pull between the two objects.
