Offer example problems for my upcoming final please?

Offer example problems for my upcoming final please?

Offer example problems for my upcoming final please?

My Physics final is this week and here are the topics my professor has said will be on it:

1.)Projectile Motion

2.)Equilibrium; rotational & translational using Σ T / Σ Fx / Σ Fy all = 0

3.)2nd law - Multiple masses

4.)energy conservation

5.)momentum(P) conservation Inelastic-1-D & elastic-2-D

6.)centripetal force 2nd law

7.)Angular momentum(L) conservation

8.)2nd law rotation [ΣT=Id]

If you could just list a possible question type for each I'd really appreciate it. Thanks, I will rate best answer

    If you just browse this Y!A section, you should find all of these question types asked and answered. Notice the search bar just below the green banner.

    Projectile Motion - search for "projectile motion". Some questions are about cannonballs. Questions about dropping things out of planes add the horizontal motion.

    Σ F = 0 - are often about friction on a ramp/slope/incline

    Σ T = 0 - search for "torque" or "pivot". Some questions are about ladders leaning against walls.

    Multiple masses - Are usually connected by a "massless rope" through a "frictionless pulley", so search for those terms. A typical problem has one mass hanging over the edge of a table, with friction on the other mass holding it up.

    energy conservation - An object slides down a frictionless ramp and then encounters a spring and/or friction, how long (time/distance) does it take to stop? Also comes up in the elastic collision problems.

    Inelastic & elastic collisions - search for these terms. Inelastic tend to feature blocks sticking together; 2D tend to feature pool balls.

    centripetal force - can be about the radius of a planet's orbit, or the acceleration of a car around a turn.

    The last two I haven't seen very often here. Searching for "angular momentum" and "moment of inertia" should be sufficient. Questions may be about figure skaters trying to slow down.

    If this is a calculus-based course, work on calculating the rotational intertia of various shapes such as a hollow sphere, a cylinder, a sphere around an axis some distance away from it.

    NOT A PSP GO, it has like no video games. I'd suggest both a psp 3000, a 3ds, or a playstation vita. PS vita is probably the most high-priced, however it additionally has the high-quality pics, controls, and on-line. If you are inclined to attend a couple of months and spend 250 bucks, get this, as there also are plenty of well downloadable and retailer video games coming. 3ds is the moment such a lot high-priced. Graphics are relatively awesome to a psp 3000, has beautiful mediocre on-line and shops, and equal controls because the psp + a contact reveal. It's additionally in 3d. Buy this if there are extra video games you favor than the vita, otherwise you can not spend 250 on a vita. psp 3000 is the most affordable. It has relatively worse pics than the 3ds, good enough on-line and shops, and equal controls as 3ds with out the contact reveal. Its in second. Don't purchase until there are a ton of video games you wish and also you can not spend 250 on a vita, as plenty of psp video games will come to vita. Overall, purchase the only with probably the most video games you wish. But if they are approximately identical, opt for the vita. if for a few cause you can not get the vita, the 3ds. If for a few cause you can not get the 3ds, the psp 3000
