Acceleration toward the center of a circular path is called?
Centripetal Acceleration
200
What are the main types of friction?

300
The rule describing the mutual attraction between any two objects with mass is called
the universal law of gravitation
300
What are three types of kinetic friction?
Rolling Friction Fluid Friction Sliding Friction
300
what is the formula for density?
Density= Mass/ Volume
400
A force that is at rest called________________.
balanced force
400
State Newton's 2nd law.
The more mass an object has the more acceleration you will need to move that object.
400
Centrifugal does not exist (T or F)
True
400
Where does fluid friction occur?
In liquid and in gas
400
Occurs when an object placed into a fluid moves some of that fluid aside to make room for itself called?
Fluid Displacement
500
the study of forces and their effect is called____________.
dynamics
500
when you hammer a nail, the hammer is exerting force on the nail, and a force is exerted right back on the hammer, which you can feel. This is a example of what law?
Newton's third law
500
What are the factors that affects centripetal force and why?
Mass- the larger an object, the force it takes to move it. Speed- The faster an object moves, the more force it takes to keep it moving at that speed. Radius- It will take more force to make an object move in a smaller circle.
500
What are the factors determining strength of the force of friction?
The types of surface involved How hard the surfaces are pushed together
500
In order for an object to float, the mass of the object has to ____________ and the volume of the fluid has to ___________.
Decrease; Increase
