1. Motion and Energy
Motion- An object is in Motion when ________________________________________________________________________________________________________

2. Motion- An object is in Motion when It changes positions
Motion and Energy
Motion- An object is in Motion when
It changes positions
Reference point -
A place or object that can be used to determine if an object is in motion

3. Speed= _______________________________________________________
Motion and Energy
Speed=

4. Speed = Distance divided by Time
Motion and Energy
Speed =
Distance divided by Time

5. Velocity - ____________________________________________________

6. The speed of an object moving in a particular direction
Motion and Energy
Velocity –
The speed of an object moving in a particular direction
Such as: N,S,E,W
Or: left, right, up, down

7. Motion and Energy Velocity –
The velocity of the airplane is defined by both its direction and speed.

8. Motion and Energy Velocity –
The rate at which the velocity of an object changes is called acceleration.
That means that an object is accelerating whenever it speeds up, slows down or changes direction.

9. Motion and Energy A Force is a push or pull
Forces act upon your Motion: your ability to move, speed up, or change direction

10. Unbalanced Force acting on an object will change the object’s motion.
Motion and Energy
Unbalanced Force acting on an object will change the object’s motion.

11. Equal forces that act on an object in opposite directions are called Balanced Forces.

12. Motion and Energy
Net Force -The overall Force acting on an object
Expressed in Newtons
(N)

13. NET FORCE Add = Subtract = Help each other Going same direction
Oppose each other
Go against

14. LET’S PRACTICE:

15. Calculating NET FORCE Net Force= 17N Net Force= 50 N Net Force= 7 N
