Physics

3. a quantity having direction as well as magnitude, especially as determining the position of one point in space relative to another
7. the force acting between two surfaces that are sliding past each other
8. the resistance that one surface or object encounters when moving over another
10. a graphical illustration used to visualize the applied forces, moments, and resulting reactions on a free body in a given condition
12. a force that acts to keep an object stationary, preventing it from moving
13. the quantity of motion of a moving body, measured as a product of its mass and velocity
15. the combined effect of all the forces on the object's acceleration,
16. the speed of something in a given direction
17. the action or process of moving or being moved
18. the rate of change of velocity per unit of time
19. the moving of something from its place or position
20. the universal force of attraction acting between all bodies of matter

1. a dimensionless number that describes the amount of resistance an object encounters when trying to slide across a surface
2. states that an object will remain at rest or continue moving in a straight line at a constant speed unless acted upon by an external force
4. a tendency to do nothing or to remain unchanged
5. base unit for measuring mass
6. the force needed to accelerate a mass of one kilogram by one meter per second squared
8. strength or energy as an attribute of physical action or movement
9. states that the force acting on an object is equal to the object's mass multiplied by its acceleration
11. the quantity of matter which a body contains, as measured by its acceleration under a given force or by the force exerted on it by a gravitational field
14. states that "for every action, there is an equal and opposite reaction,"
