Orbits

The curved path of an object around a point or object in space is:

• The object's orbit

• The object's rotation

• The object's gravity

• The object's weight

What prevents planets from being pulled into the Sun?

• Gravity

• Weight

• Friction

• Inertia (movement)

The Earth doesn't crash into the Sun, because:

• it's moving slow enough it doesn't fly off

• it's moving fast enough to orbit

• it's too heavy to pull in

• it's too far away for gravity to pull it down

Gravitational forces are always:

• Attractive

• Pushing

• Repulsive

• Increasing

Mass has a directly proportional relationship with gravity which means when mass increases, gravity:

• Also increases

• Decreases

• Stays the same

The planets of our solar system have orbits that are:

• circular

• elliptical

• parabolic

• linear

The point in its orbit where a planet (or other orbiting object) is farthest from the Sun is called:

• aphelion

• apogee

• eccentricity

• perihelion

When the moon is the closest to the Earth, its position is called:

• perihelion

• perigee

• apogee

• aphelion

• axis

• vector

• arrows
