Exam review notes

12AP Exam review. 2 days.

The Electromagnetic spectrum: find 3 other parts in order.

Radio waves, , , , gamma radiation

As you go from left to right, wavelength_______________ frequency_______________ and the

speed ______________________________________

What was Millikan looking for?

He needed to get the mass. He measured the ___________________ velocity in air

What 2 forces did he balance to find q for each droplet?

Once he had many values for q, he forced his grad students to spends hours and weeks looking for the _________________ common _______________ with NO CALCULATOR!!!

An electron moving East deflects upward. The direction of the electric field must be ___________

When 2 objects collided completely elastically, what is conserved?

In an Elastic collision, under what conditions does m1 move forward after the collision?

In an Elastic collision, under what conditions does m1 stop after the collision?

Under what conditions is p=p’?

What is root of G/Mr __________________ What is root of 2 G/Mr ________________

How can you calculate the change in Eg accurately for large changes in elevations?

How can you calculate the K accurately for high speeds

What is a satellite?

What does geosynchronous mean?

As you move further from the sun, the period of the planets ________________and the speed of the planets ___________________. Use basic principles (starting with the FBD of a satellite) to show why.

If Ta/Tb= 3 what is Ra/Rb (for 2 moons of the same planet)

If you travelled to a distant planet, how could you determine its mass?

A object slides on a horizontal surface with uK of 0.5. At what rate does it slow down? Use an FBD to explain your answer.

How can you determine how far it will slide if you know its original speed using conservation of energy?

2 equally charged objects are held together and one of them is released. What happens to their speed and acceleration as they move further apart.

Why do you have to use conservation f energy to solve for v (as opposed to the kinematics equation?)

Can you use the kinematic equations to solve for the motion of charged particles between charged plates? Why or why not?

In uniform circular motion, the direction of the net force is ________________________________

and the _________________ are/is uniform?

For the points on the second hand of a clock, as you move further from the center the acceleration ______________. A car makes 2 turns at the same speed. The turn with the greater r has a _______________ acceleration. Explain.

Explain how you would find the potential and field at the midpoint between 2 point charges.

The potential near a positive charge is always _________________. Why?

Explain how you would find the maximum speed of 2 equal mass and signed charges when they are both released.

How does this calculation change if only one of the charges is released?

Explain how you calculated the spring constant for the lab carts.

Explain how you would calculate the % diff of P and % loss of K for part A of the collisions lab

Is it possible to move to a region of greater gravitational potential energy and lose Eg?

Why?

Is it possible for a charged particle to move to a region of greater electric potential and lose EPE?

Why?

You are flying towards the Earth. Who measures the proper length for the distant you are from the Earth?

You will measure this distant to be _________________ than this length.
