Gravity and Terminal Velocity

Front

What is gravitational attraction?

Back

Gravitational attraction is the force that pulls two objects toward each other, proportional to their masses and inversely proportional to the square of the distance between their centers.

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, which does not change regardless of location. Weight is the force exerted by gravity on that mass, which can change depending on the gravitational field.

Front

What is terminal velocity?

Back

Terminal velocity is the constant speed that a freely falling object eventually reaches when the resistance of the medium (like air) prevents further acceleration.

Front

What role does air resistance play in falling objects?

Back

Air resistance opposes the motion of falling objects, causing them to slow down until they reach terminal velocity.

What happens to the gravitational force as the distance between two objects increases?

Back

The gravitational force decreases as the distance between two objects increases, following the inverse square law.

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 their centers.

In a vacuum, how do objects fall?

Back

In a vacuum, all objects fall at the same rate regardless of their mass, as there is no air resistance to slow them down.

What is the significance of Galileo's experiments with falling objects?

Back

Galileo's experiments demonstrated that the acceleration of falling objects is constant and independent of their mass, laying the groundwork for the understanding of gravity.

What is the effect of gravity on the motion of planets?

Back

Gravity is the force that keeps planets in orbit around stars, such as the Earth orbiting the Sun, due to the gravitational attraction between them.

What is the relationship between gravitational force and mass?

Back

The gravitational force between two objects increases with the mass of either object; the greater the mass, the stronger the gravitational attraction.
