This is the formula for centripetal acceleration when you know velocity.
What is a=v^2/r?
100
This is the source of centripetal force when a car is driving around a corner.
What is friction?
100
This is the formula for universal gravitation.
What is F=GMm/r^2?
100
This is the formula for the force between two charges.
What is F=kQq/r^2?
100
If you know the electric field, this formula will tell you the force.
What is E=F/Q?
200
This is how to find the centripetal force if you know the centripetal acceleration.
What is F=ma?
200
This is the source of centripetal force when a satellite is orbiting Earth.
What is gravity?
200
This is G.
What is 6.67x10^-11?
200
This is what Q stands for.
What is charge?
200
If you know the change in electric potential, this formula will tell you the change in potential energy.
What is Delta V = Delta E_p / Q ?
300
A ball is being swung on a rope.
F_c=40N
F_g=30N
This is the tension in the rope when the ball it at the top.
What is 10N?
300
These are the sources of centripetal force when a car drives over a speed bump.
What are gravity and normal force?
300
This is what you would need to calculate in order to determine the work required to move an object.
What is potential energy?
300
This is what you first need to calculate if you want to determine the final speed of a particle. (I'm looking for a quantity in the electrostatics section)
What is potential energy?
300
This formula tells you the electric field between two parallel plates (e.g. in a capacitor).
What is E = Delta V / d ?
400
A ball is being swung on a rope.
F_c=40N
F_g=30N
This is the tension in the rope when the ball it at the bottom.
What is 70N?
400
A car is driving over a speed bump.
Fg=1000N
Fc=1200N
This is whether the car will fly off the speed bump.
What is very yes?
400
This is whether masses are attracted to regions of low potential energy or regions of high potential energy.
What is they are attracted to regions of low potential energy (i.e. large negative potential energy)?
400
These are two other names of voltage.
What are electrostatic potential and electromotive force (emf)?
400
This is how to draw a smiley face.
What is :) ?
500
A ball is being swung on a rope.
F_c=40N
F_g=30N
This is the tension in the rope when the ball it at the side.
What is 40N?
500
A car is crossing a ditch.
Fg=1000N
Fc=1200N
This is whether the car will crash in the ditch.
What is hopefully not?
500
This is the formula for the strength of the gravitational field (hint: it is similar to the formula for the strength of the electrostatic field).
What is GM/r^2?
500
This is the formula for the electric potential from a 5.0uC charge at a 2.0uC which is 0.1m away from it. (hint: your formula for electric potential only uses one charge... but which one?)
What is V=(9x10^9)(5.0uC)/(0.1)?
500
This is the formula you would use if you wanted to find the final speed of a particle after it is accelerated by a change in voltage. (I'm looking for a formula in the electrostatics section).
