Universal Gravitation

Front

What is Newton's Law of Universal Gravitation?

Back

F = Gm₁m₂/r², 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

What two factors affect the magnitude of the gravitational force between two objects?

Back

Mass and distance.

Front

How does the force of gravity relate to mass?

Back

The force of gravity is directly proportional to the mass of the objects involved.

Front

True or False: Gravity attracts all objects towards one another.

Back

True.

Front

What happens to the gravitational force if both masses are doubled while keeping the distance constant?

Back

The gravitational force becomes 4 times bigger.

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

What is the relationship between gravitational force and distance?

Back

The gravitational force is inversely proportional to the square of the distance between the centers of two objects.

Front

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

Back

The gravitational force becomes 1/9 as strong.

Front

What is the formula to calculate gravitational force?

Back

F = Gm₁m₂/r².

Front

What is weight in terms of gravitational force?

Back

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