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

Is gravity a push or a pull?

Back

Gravity is a pull.

Front

What two factors determine the strength of gravity between two objects?

Back

Mass and distance.

Front

When does gravity have the greatest effect between two objects?

Back

When the masses of both objects are large and the objects are close together.

Front

What happens to gravity if the mass of an object increases?

Back

More mass equals more gravity.

Front

True or False: An object with mass has gravity.

Back

True.

Front

What is the relationship between distance and gravity?

Back

As distance increases, the force of gravity 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 of the objects, and r is the distance between their centers.

Front

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).

Front

How does gravity affect objects in free fall?

Back

All objects in free fall accelerate towards the Earth at the same rate, regardless of their mass.
