1. Displacement
change of the position. The final position minus the initial position
2. Avgerage Velocity
The average distance over an average time
3. Acceleration
Rate of change of the velocity
4. Free Fall
No forces act on an object other than the gravitational force that makes the object fall
5. Vector
Have both magnitude and direction.
6. Force
A push or pull that one object exerts on another
7. Weight
Magnitude of the gravitational force that a planet or moon exterts on a nearby object
8. Inertia
Resistance to changes in velocity
9. Kinetic Friction
When the two objects are slipping or sliding across one another, as when a loose shingl slides down a roof.
10. Static friction
No slipping or sliding occurs, as between the tires of a car parked on a hill and the road surface
11. Conservation Law
Physical law that identifies a quantity that does not change wth time
12. Kinetic energy
Energy due to motion
13. Potential Energy
Stored energy due to interaction
14. Translation
Motion of an object in which any point of the object moves with the same velocity as any other point. (object does not rotate or change shape)
15. Work
Energy transfer that occurs when a force acts on an object that moves
16. Mechanical Energy
the sum of the kinetic and potential energies
17. Power
Rate a which work is performed or evergy is converted
18. Linear Momentum
Product of mass and velocity
19. Impulse
Product of a vector and a positive scalar
20. Center of Mass
An average location of the system (a point)
21. Torque
Role in otation that force itself plays in translation. A measure of how effective a given force is at twisting or turning something
22. Center of Gravity
Total force of gravity can be considered to act at a single point
23. Fluids
materials that flow and include both liquids and gases. Nearly incompressible
24. Pressure
Force per unti area is the same for any orientation of the surface
25. Density
mass per unit volume
26. Buoyant force
total force on an object due to fluid
27. Archimedes Principle
The buoyant force on an object is equal to the weight of an equal volume of fluid
28. Bernoulli Effect
Fluid flows faster where the pressure is lower
29. Surface tension
the force per unit lenght with which the surface pulls in its edge
