1. FRICTION IN OUR FELLOWSHIP
WRITE 2 “FRICTIONS” YOU HAVE HAD WITH ANOTHER CHRISTIAN.
HOW WOULD CHRIST WANT YOU TO HANDLE IT
HOW WOULD DOING 2 HELP REDUCE FRICTION IN OUR FELLOWSHIP?

2. Reducing Friction in Our Fellowship
 In Jesus' comments about judgment in His Sermon on the Mount, He warned us about being too critical of others(Matthew 7:3).
So, when we find ourselves offended by anyone, instead of being mean, we should apply the principle of giving a soft answer (Proverbs 15:1) and forgive as Christ forgave us.
Because we do life together at times we have friction and rub each other the wrong way. Satan would like us to hang on to evil thoughts about another, to hold a grudge against a brother, or to arrive at church/school with a bad attitude toward a fellow Christian,

3. Reducing Friction in Our Fellowship
Jesus wants us to FORGIVE just as He forgave each of us from the heart, He wants us to learn to forgive others in the same generous, merciful way.

4. Newton’s Laws of Motion

5. To understand the the motion of an object, you need to to understand the forces acting on it

6. When two or more forces act on an object, the forces combine

7. The combination of all forces that act on an object is the net force.

8. Net Force
When the forces applied to an object act in the same direction the net force is the SUM of the individual forces.

9. Net Force
Forces have direction so remember to specify a REFERENCE DIRECTION. Forces in opposite directions are positive and negative. Net =SUM of forces.

10. Forces that combine and form a net force of zero are BALANCED FORCES
An object at rest tends to stay at rest unless acted acted on by a force.
The lemons sitting on the table are not in WHY?

11. If the net is NOT zero the forces are unbalanced forces
If the net is NOT zero the forces are unbalanced forces. Does that change motion?

12. Newton’s 1st Law of Motion
An object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Also called the Law of Inertia
Sir Isaac Newton ( ), mathematician and physicist, one of the foremost scientific intellects of all time.

13. Inertia
When balanced forces act on the lemons the velocity does not change.
An object at rest tends to stay at rest unless acted on by a force.

14. Inertia
If unbalanced forces act on a moving object, the object will change it’s velocity.
What forces are acting here?

23. Demonstration! Accelerating Car
Design a vehicle that has a flat surface. Place a passenger (weight), then quickly accelerate.
What happens? How does this relate to Newton’s First and Third Law?

25. Answer: The heavy weight wanted to stay at rest and didn’t go into motion with the car.

26. Petri-Dish taped to Scooter
Demonstration! Place a ball on a scooter board, move in a straight line with attached rope, then turn the scooter board to the side.
What direction does the ball travel?

29. Answer: The ball rolled in a straight line because an object in motion wants to stay in motion and in the same direction.
