Gravity

Front

What is gravity?

Back

The force that pulls everything toward the center of the Earth.

Front

Who was the first person to study gravity?

Back

Isaac Newton.

Front

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

Back

Mass and distance.

Front

What happens to gravitational attraction if both masses are increased and the distance between them is decreased?

Back

The gravitational attraction increases.

Front

What is mass?

Back

The amount of matter in an object, which does not change regardless of gravity.

Front

What is weight?

Back

The force of gravity acting on an object, which can change depending on the gravitational field.

Front

How does distance affect gravitational force?

Back

As the distance between two objects increases, the gravitational force decreases.

Front

What is the relationship between mass and gravitational force?

Back

Greater mass results in a stronger gravitational force.

Front

What is the formula for gravitational force?

Back

F = G * (m1 * m2) / r^2, where F is the force, G is the gravitational constant, m1 and m2 are the masses, and r is the distance between their centers.

Front

What is the gravitational constant (G)?

Back

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