Unit 10 PreAssessment

Front

What three objects cause ocean tides due to gravitational pull?

Back

Earth, the Moon, the Sun

Front

How does mass affect gravitational pull?

Back

The larger the mass, the larger the gravitational pull of an object.

Front

What two variables determine gravitational pull?

Back

Distance between the objects and masses of the objects.

Front

What happens to gravitational pull as distance increases?

Back

The gravitational pull on an object decreases.

Front

What force is responsible for the movement of all objects within our solar system?

Back

Gravity.

Front

Define gravity.

Back

Gravity is the force that attracts two bodies toward each other.

Front

What is the relationship between mass and gravitational force?

Back

Gravitational force increases with mass.

Front

How does distance affect gravitational force?

Back

Gravitational force decreases as distance increases.

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 the centers.

Front

What is the gravitational pull of the Earth on an object?

Back

Approximately 9.81 m/s².
