Science U4 Lesson 1-5

What is gravity?

• A force of attraction that pulls objects without them touching. Earth’s gravity pulls objects near its surface toward Earth’s center.

• The streak of light that a chunk of rock falling from space toward Earth produces

• A curved path that an object makes around another object.

• A measurement describing how bright a star looks from Earth.
