Gravity Review

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, proportional to their masses and inversely proportional to the square of the distance between their centers.

Front

True or False: Gravity attracts all objects towards one another.

Back

True

Front

What is the relationship between mass and gravitational force?

Back

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

Front

What is the term for the amount of matter in an object?

Back

Mass.

Front

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

Back

Model A (assuming it has greater mass or is closer to the other object).

Front

True or False: Gravitational force is another name for gravity.

Back

True.

Front

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

Back

The gravitational force decreases.

Front

What is the formula for calculating gravitational force between two masses?

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 of the two masses.

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

How does the mass of an object affect its weight?

Back

Weight is the force of gravity acting on an object's mass; therefore, greater mass results in greater weight.
