7. Tale of Momentum & Inertia

8. Newton and the Study of Gravity
Why do objects fall toward Earth…and…what keeps the planets moving in the sky?
Gravitational force increases as mass increases.
Gravitational force decreases as distance increases.

9. Gravity and Motion

10. Newton’s Laws of Motion
Force and motion are related.

11. Newton’s 1st Law= Law of Inertia
An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force.

12. What does that law mean?
Objects will not start moving until a push or pull is exerted on them.
Objects will continue to move forever unless something interferes.

13. When I kick a ball, why doesn’t the ball keep going on forever…if things in motion stay in motion?
FRICTION and GRAVITY

14. When you ride in a car, why do you fall forward when the car stops moving?

15. 1st Law = Law of Inertia
1st Law Key Term: Inertia—the tendency of all objects to resist any change in motion

16. Use Newton’s first law of motion to explain why airbags in cars are important during head-on collisions.
