Forms of Energy

Front

Energy cannot be created or destroyed in any reaction. This law is known as......

What two factors affect the strength or force of gravity between two objects? Options: mass and speed, speed and distance, mass and distance, heat and composition

Back

mass and distance

Front

Why is the force of gravity important to the Earth and Moon?

Back

Gravity keeps the Earth in orbit around the Sun and Moon in orbit around the Earth.

Front

The reason the Moon orbits the Earth, and the Earth orbits the sun (and not the other way around) is:

Back

smaller massed objects in space orbit those with larger masses
