What is gravity?

Back

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

What is the difference between weight and mass?

Back

Weight is the force exerted by gravity on an object, while mass is the amount of matter in an object, which does not change regardless of location.

What happens to gravitational attraction in space?

Back

Gravitational attraction remains the same in space as long as the mass and distance between objects do not change.

What is terminal velocity?

Back

Terminal velocity is the constant speed an object reaches when the force of gravity is balanced by the drag force of the medium through which it is falling.

How does mass affect gravitational force?

Back

If the mass of one object increases while the other remains the same, the gravitational force between them increases.

What is microgravity?

Back

Microgravity is a condition in which objects appear to be weightless and experience very small gravitational forces, often found in space.

What is the formula for 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, and r is the distance between their centers.

What is the effect of distance on gravitational force?

Back

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

What is the weight of an object on Earth?

Back

The weight of an object on Earth is calculated by multiplying its mass by the acceleration due to gravity (9.8 m/s²).
