1. Define force
Push or pull action
2. Define vector
Quantity of magnitude and direction
3. Define velocity
A vector that describes speed or displacement
4. Define scalar
Only describes magnitude
5. Define mass
Amount of matter body contains
6. Define inertia
Resistance to change
7. Define torque
Force will produce rotation around an axis
8. Define friction
Motion of one surface across another
9. What's newton first law of motion
Inertia. an object at rest stays at rest, a object in motion stays in motion
10. What's newton second law of motion
Acceleration depends on the strength of the force applied to an object
11. What's Newton's third law
Action reaction law. for every action there is an equal and opposite reaction
12. What's a linear force
Two or more forces acting the same plane
13. What's a concurrent force
Forces using a common point but push or pull in divergent directions
14. What's a resultant force
Net effect of two divergent forces
15. What's a force couple
Two or more forces acting in equal force but opposite directions
16. What is COG
• Balance point of an object
• Center of gravity about S2 when standing
17. What is BOS
body in contact with support surface
18. what is LOG
vertical line of gravity passing through COG
19. What's is LOB
Loss of balance COG outside BOS
