Physics Test #3

The product of the mass of an object and its velocity or p=mv Momentum
Pascals Princple deals with Pressure
Pressure id defined as the ratio of force to area exerted on by a fulid Pascals Princple
pressure extends uniformly in all directions through a fluid which explains the operation of hydraulic systems Pascals Princple
P=f/a pressure formula
We can measure atmospheric pressure by determining the height of a column of mercury supported by the atmosphere
atmospheric pressure decreases with increasing altitude
The density of air changes with altitude because a lower pressure leads to a larger volume Boyles Law
In a fluid pressure increase with depth producing a buyoant force on objects submerged in the fluid
Force is equal to the weight of the fluid displaced by the object Archimedes principle ex ice floating in water
The rate of flow of a fluid is.. equal to the speed times the cross sectional area.
In continous flow the speed increases if the area decreases
Fluids with high viscosity have a greater resistance to flow than those with low visocity.
As the flow increases the flow may change from laminar (smooth) to turbulent flow
energy considerations require that the kinetic energy per unit mass of a fluid increase as the pressure decreases Bernoullis Princple
Can be used to explain the curve of a curveball Bernoullis Princple
Density mass/volume
Pressure p=f/a
Viscocity the property of fluid that determines the strength of frictional forces between the layers of fluid
The larger the viscocity the larger the frictional force
Rotational motion rotational displacment is described by an angle 0
Rotational velocity the rate of change of an angle with time w= 0/t
Rotational acceleration the rate of rotational velocity with time a=w/t
Torque what causes an object to rotate
Torque force times the lever arm of the force which is perpendicular distance from the line of action of the force to the axis of rotation
if the net torque is zero the object does not change its state of rotation.
rotational interia depends on the distribution of mass about an object
angular momentum the rotational interia times the roational velocity
fulcurm pivot point
Center of gravity the point about which the weight of the object itself exerts no net torque
Conservation of momentum the net force external force acting on a system is zero the total momentum of the system is a constant
impulse the average force acting on an object multipied
Recoli (football player problem) p1=-p2

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
