Gravity

Front

What is gravity?

Back

Gravity is a force that attracts two bodies toward each other, proportional to their masses and inversely proportional to the square of the distance between their centers.

Front

What keeps planets in orbit around the sun?

Back

Gravity is the force that keeps planets in orbit around the sun.

Front

Which has more mass, the Earth or the Moon?

Back

The Earth has more mass than the Moon.

Front

How does distance affect the pull of gravity?

Back

As the distance between two objects increases, the pull of gravity decreases.

Front

What is the relationship between mass and gravitational attraction?

Back

The greater the mass of an object, the greater its gravitational attraction.

Front

Why does Mars have less gravity than Earth?

Back

Mars has less gravity than Earth because it has less mass.

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 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 is the gravitational constant (G)?

Back

The gravitational constant (G) is approximately 6.674 × 10^-11 N(m/kg)^2, a proportionality factor in the equation for gravitational force.

Front

How does gravitational force change with distance?

Back

Gravitational force decreases with the square of the distance between two objects.

Front

What is the effect of gravity on 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.
