Gravity

Front

Who was the first person to describe gravity?

Back

Sir Isaac Newton

Front

What is the relationship between mass and gravitational force?

Back

As mass increases, gravitational force increases.

Front

Which model has greater gravitational attraction if any: Model A or Model B?

Back

Model A has greater gravitational attraction.

Front

What is gravitational attraction?

Back

Gravitational attraction is the force that pulls two objects toward each other, proportional to their masses.

Front

True or False: The sun's gravity is powerful enough to pull on all the planets in the solar system.

Back

True

Front

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

Back

Gravitational force decreases as distance increases.

Front

What is the formula for gravitational force?

Back

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

Front

What is the gravitational constant (G)?

Back

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

Front

What is weight?

Back

Weight is the force exerted by gravity on an object, calculated as weight = mass × gravitational acceleration.

Front

What is gravitational acceleration on Earth?

Back

Gravitational acceleration on Earth is approximately 9.81 m/s².
