Unit 5 Review

Front

Where is the planet moving faster?

Back

The planet moves faster around segment A due to its proximity to the sun, as per Kepler's laws of planetary motion.

Front

What effect does increasing the distance between two objects have on the gravitational force?

Back

Increasing the distance between two objects decreases the gravitational force between them, according to the inverse square law.

Front

What does Kepler's 2nd Law state?

Back

Kepler's 2nd Law states that a line segment joining a planet and the sun sweeps out equal areas during equal intervals of time, meaning the planet travels faster when closer to the sun.

Front

What happens to the pull of gravity as the product of two objects' masses increases?

Back

As the product of two objects' masses increases, the pull of gravity between them increases.

Front

What is true about the gravitational force between a baseball and a bat on the ground?

Back

The baseball and bat attract each other with equal gravitational force, regardless of their masses.

Front

Define gravitational force.

Back

Gravitational force is the attractive force between two masses, proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Front

What is Kepler's 1st Law?

Back

Kepler's 1st Law states that planets move in elliptical orbits with the sun at one focus.

Front

Explain the concept of inertia in relation to planetary motion.

Back

Inertia is the tendency of an object to resist changes in its state of motion; in planetary motion, it keeps planets moving in their orbits.

Front

What is the relationship between mass and gravitational force?

Back

The gravitational force is directly proportional to the masses of the objects involved; greater mass results in a stronger gravitational pull.

Front

What is the formula for gravitational force?

Back

The formula for gravitational force is 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.
