1. Motion In Review Newton’s Toy Box Activity 1

2. Vocabulary Force Inertia Newton’s first Law of Motion Velocity

3. What is a Force Force is a Push or Pull Examples of Force: Gravity Friction Electricity Magnatism

4. Gravity Gravity is the force that pulls us towards the earth. It gives everything a weight If gravity didn’t exist we would float around like astronauts in space

5. Friction What do you notice about the soles of your shoes? There are patterns of ridges which are designed to stop you from slipping. A force called friction is created when 2 or more surfaces rub together. The greater the friction the more the 2 surfaces grip.

6. Sir Isaac Newton He discovered the principles that explain how things move on Earth’s surface and in space.

7. Begin Activity Do steps 1-3 Stop after completing step 3

8. What is Velocity Velocity is speed in a particular direction. Velocity includes both speed and direction. A moving object that changes speed but continues moving in the same direction has changed it’s velocity. A moving object that changes direction but retains the same speed has changed its velocity.

9. Complete the Activity Use your own words in applying Newton’s first law of motion.

10. Newton’s first law of Motion An object will remain at rest or in uniform motion unless acted on by an unbalanced force.

11. Inertia The object’s tendency to remain at rest or in motion is called inertia. What one activity have you recently performed that illustrates the inertia principle.
