Gravity

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, depending on their masses and the distance between them.

Front

What is the normal force?

Back

The normal force is the support force exerted upon an object that is in contact with another stable object, acting perpendicular to the surface.

Front

How does mass affect gravitational force?

Back

The gravitational force increases as the mass of one or both objects increases.

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

What does Newton's Universal Law of Gravitation state?

Back

It states that every point mass attracts every other point mass 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 factors affect gravitational attraction between two objects?

Back

The mass of the objects and the distance between them.

Front

What is the formula for calculating gravitational force?

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 the centers.

Front

What is weight?

Back

Weight is the force of gravity acting on an object, calculated as the mass of the object multiplied by the acceleration due to gravity.

Front

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

Back

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

Front

What is the gravitational constant (G)?

Back

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