Gravity

Front

What does gravity do?

Back

Gravity is a force that attracts two bodies towards each other.

Front

What is the formula for gravitational force?

Back

The formula is 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 the gravitational constant (G)?

Back

The gravitational constant (G) is approximately 6.674 × 10^-11 N(m/kg)^2.

Front

How does mass affect gravitational force?

Back

Gravitational force increases with the mass of the objects involved.

Front

How does distance affect gravitational force?

Back

Gravitational force decreases as the distance between the objects increases.

Front

What is an example of a noncontact force?

Back

Gravity is an example of a noncontact force.

Front

What happens to gravity if the distance between two objects is halved?

Back

If the distance is halved, the gravitational force increases by a factor of four.

Front

What is the relationship between gravitational force and weight?

Back

Weight is the force of gravity acting 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.

Front

What is the effect of gravity on falling objects?

Back

All objects fall at the same rate in a vacuum, regardless of their mass, due to gravity.
