1. Motion and force

2. A force applied to an object can change the object’s motion.

3. Motion is the change in an object’s position.

4. Frame of reference is knowing if an object is moving or is at rest.

5. Newton is the scientist that discovered the laws of motion.

6. Newton’s First Law
An object at rest, stays at rest. An object in motion, stays in motion unless a force is applied.

7. A push or pull that acts on an object is called force.

8. Resistance to a change in motion is called inertia.

9. Force
Air Resistance
air

10. Speed is a measure of distance moved in a given amount of time.

11. Formula for speed Speed equals distance divided by time S=D/T
S is for speed
D is for distance
T is for time

12. Velocity
Velocity measures both speed and direction.

13. Speed
Direction. Going opposite ways.

14. Acceleration
A change in speed and direction is called acceleration.

15. Balanced force
Same amount of force on each side and therefore there is no movement.

16. Unbalanced force
There is different amounts of force coming from each side and therefore, the truck is going to move.

17. Force = mass x acceleration
F=MxA
An object’s acceleration depends on its mass and size of force acting on it.

18. Newton
Sir Isaac Newton was not only the scientist who formulated the Laws of Motion, his name is used for the units of motion.
Like inches and feet are units, newtons are units too!

19. Gravity
A force that causes objects with mass to be attracted, or pulled, toward one another is called gravity.

20. Friction
Force that resists motion of one surface to another is friction.
Air resistance or drag
