### Final Study Cards for Dynamics

What is the difference between the kinematics of a particle and the kinetics of a particle? Kinematics is the study of the geometry of a particle in motion. Kinetics is the study of this particle including forces, mass and motion.
Consider a particle in rectilinear motion with its position given by the expression x= 2t^4 + 4t^3 + 5 with x in meters and t in seconds. Find the acceleration, velocity, and position of the particle at t= 3 seconds. x(3)= 275m , v(3)= 324m/s, a(3)= 288m/s^2
For a particle in planar, curvilinear motion, how are the normal and tangental directions defined? The normal direction would be the direction perpendicular to the curve toward the center of curvature. The tangental direction would be the direction parallel to the curve at any time t.
In the analysis of planar, curvilinear motion, what are the radial and transverse coordinates? Transverse point in the direction in which P would move if * were increased and r were kept constant.(e*) Radial point in the direction in which P would move if r were increased and * were kept constant. (e r)
If a particle is traveling in a curve path, which of the following statements must be true about its normal accelerations.a) it is zerob)it is directed toward the center of curvature of the path c)it is directed away from the center of curvature of the pathd)any of the above may be true-b-
If particles A and B have velocity vectors Va= 4i + 3j and Vb= 5i - 2j, find the relative velocity vector Va/b Vb-Va= i-5j
While watching a figure skating competition, it is observed that a skater begins a spin with her arms extended and then pulls them in toward her body.As she pulls in, the rate of spin increases.What principle of dynamics explains this phenomenon? conservation of angular momentum

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:

• SPACEBAR - flip the current card
• LEFT ARROW - move card to the Don't know pile
• RIGHT ARROW - move card to Know pile
• BACKSPACE - undo the previous action

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.

To see how well you know the information, try the Quiz or Test activity.
