4 Gravity

Front

What is gravity?

Back

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

Front

How does mass affect gravity?

Back

The greater the mass of an object, the stronger the gravitational force it exerts.

Front

What happens to weight as you move away from Earth?

Back

Weight decreases as you move further from Earth because gravitational force weakens with distance.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object and remains constant, while weight is the force of gravity acting on that mass and can change depending on location.

Front

What would happen to a feather and a bowling ball in a vacuum?

Back

Both would hit the ground at the same time because, in a vacuum, there is no air resistance.

Front

What is the relationship between distance and gravitational force?

Back

The gravitational force decreases as the distance between two objects increases.

Front

What is an example of gravity in everyday life?

Back

An example of gravity is when an apple falls from a tree to the ground.

Front

What role does gravity play in the solar system?

Back

Gravity keeps planets in orbit around the sun and moons in orbit around planets.

Front

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 the centers of the two masses.

Front

What is the gravitational constant?

Back

The gravitational constant (G) is approximately 6.674 × 10^-11 N(m/kg)^2 and is used in the calculation of gravitational force.
