STUDY GUIDE: Topic 1 Lesson 3 and 4

What is the 1st Law of Motion?

• An object at rest will stay at rest and an object in motion will stay in motion unless acted on by an outside force.

• The acceleration of an object depends on the force applied and how much mass.

• For every action, there is an equal and opposite reaction.

• Resistance to change in motion.
