1. Chapter 6- Forces and Motion By Samantha Pereira

2. Chapter Summary This chapter is about gravity and motion, Sir Isaac Newton’s Laws about motion, and momentum, what keeps you going. This chapter is about gravity and motion, Sir Isaac Newton’s Laws about motion, and momentum, what keeps you going.

3. Lesson 1- Gravity and Motion

4. Lesson 1 Vocabulary Terminal velocity-when the object falls at a constant velocity Terminal velocity-when the object falls at a constant velocity Free fall- the motion if a body when only the force of gravity is acting on the body Free fall- the motion if a body when only the force of gravity is acting on the body Projectile motion- the curved path an object follows when it is thrown or propelled near the surface of the Earth Projectile motion- the curved path an object follows when it is thrown or propelled near the surface of the Earth

5. Lesson Summary Gravity causes all objects to accelerate toward Earth at a rate of 9.8 m/s/s. Gravity causes all objects to accelerate toward Earth at a rate of 9.8 m/s/s. An object is in free fall if gravity is the only force acting on it An object is in free fall if gravity is the only force acting on it

6. Lesson 2- Newton’s Laws of Motion

7. Lesson 2 Vocabulary Inertia- the tendency of an object to resist any change in motion Inertia- the tendency of an object to resist any change in motion

8. Lesson Summary Newton’s first law of motion states that the motion of an object will not change if no unbalanced forces act on it. Newton’s first law of motion states that the motion of an object will not change if no unbalanced forces act on it. Objects at rest will not move unless acted upon by an unbalanced force Objects at rest will not move unless acted upon by an unbalanced force

9. Lesson 3- Momentum

10. Lesson 3 Vocabulary Momentum- a quantity defined as the product of the mass and velocity of an object Momentum- a quantity defined as the product of the mass and velocity of an object

11. Lesson Summary Momentum is a property of moving objects. Momentum is a property of moving objects. Momentum is calculating by multiplying the mass of an object by the object’s velocity Momentum is calculating by multiplying the mass of an object by the object’s velocity
