Gravity

What is gravity?

Back

Gravity is a natural phenomenon by which all things with mass are brought toward one another, including planets, stars, galaxies, and even light.

Front

What is the formula for calculating gravitational force?

Back

The formula for gravitational force 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 the centers of the two masses.

What is the significance of the 1st Law of Motion?

Back

The 1st Law of Motion, also known as the Law of Inertia, states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by a net external force.

Front

What is the significance of the 2nd Law of Motion?

Back

The 2nd Law of Motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass, expressed as F = ma.

Front

What is the significance of the 3rd Law of Motion?

Back

The 3rd Law of Motion states that for every action, there is an equal and opposite reaction.

Front

How does mass affect gravitational pull?

Back

The gravitational pull between two objects increases with the mass of the objects; larger masses exert a stronger gravitational force.

Front

What role does distance play in gravitational force?

Back

Gravitational force decreases with the square of the distance between the centers of two masses; as distance increases, gravitational force decreases.

Front

What is the gravitational constant (G)?

Back

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

Front

What is the relationship between gravity and weight?

Back

Weight is the force exerted by gravity on an object, calculated as the product of mass and gravitational acceleration (W = mg).

Front

What is the difference between mass and weight?

Back

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