What happens to a feather and a hammer dropped on the moon?

Back

Both will hit the ground at the same time, as there is no wind resistance.

Front

What does the strength of gravity depend on?

Back

The strength of gravity depends on the mass of the objects and the distance between them.

What is the effect of air resistance on falling objects?

Back

Air resistance can slow down the fall of lighter objects, like a feather, in an atmosphere.

Front

How does mass affect gravitational force?

Back

Greater mass results in a stronger gravitational force between two objects.

What is the relationship between distance and gravitational force?

Back

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

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 their centers.

What is the gravitational constant (G)?

Back

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

What is weight?

Back

Weight is the force of gravity acting on an object, calculated as mass times the acceleration due to gravity (W = m * g).
