BrainPop Gravity Flashcard

Front

What happens to the gravitational pull on the Earth if its orbit moves farther away from the Sun?

Back

The Sun's gravitational pull on the Earth would decrease.

Front

What theory did Albert Einstein introduce to challenge Newton's ideas about gravity?

Back

The theory of relativity.

Front

According to Einstein, how does gravity affect space?

Back

Gravity bends space.

Front

What is the definition of gravity?

Back

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

Front

What effect does the Moon's gravity have on Earth?

Back

The Moon's gravity causes the tides on Earth.

Front

What is the relationship between mass and gravitational force?

Back

The gravitational force between two objects increases with greater mass.

Front

How does distance affect gravitational force?

Back

The gravitational force decreases as the distance between two objects increases.

Front

What is the formula for calculating 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 significance of the gravitational constant (G)?

Back

The gravitational constant (G) is a proportionality factor used in the calculation of gravitational force between two masses.

Front

What role does gravity play in the formation of planets and stars?

Back

Gravity pulls together gas and dust in space to form planets and stars.
