Forces, Densities, and Gravitational Attraction

Front

What is a force?

Back

A force is a push or pull that can change the motion of an object.

Front

What is gravitational attraction?

Back

Gravitational attraction is the force that pulls two objects toward each other, depending on their masses and the distance between them.

Front

What is density?

Back

Density is the mass of an object divided by its volume, often expressed in grams per cubic centimeter (g/cm³).

Front

How does distance affect gravitational attraction?

Back

The gravitational pull weakens as the distance between objects increases.

Front

What happens to tides during a full moon?

Back

During a full moon, the tides are typically higher due to the alignment of the Earth, moon, and sun.

Front

What is the difference between transverse and longitudinal waves?

Back

In transverse waves, the medium moves perpendicular to the direction of the wave, while in longitudinal waves, the medium moves parallel to the direction of the wave.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object based on its position or state.

Front

What is the relationship between mass and gravitational attraction?

Back

The greater the mass of an object, the stronger its gravitational attraction.

Front

What is the significance of the spring equinox?

Back

The spring equinox marks the beginning of spring in the Northern Hemisphere when day and night are approximately equal in length.
