Centripetal acceleration: The acceleration of an object due to it’s changing direction as it moves at a constant speed in a circular path. Always directed toward the center of the circle
Torque: A force applied at a distance from the pivot to produce a rotation.
momentum: The product of the mass and velocity. impulse: The product of the average force applied and the time is equal to the change in momentum
kinetic energy – Energy of motion gravitational potential energy – Energy due to position in a gravitational field Elastic potential energy – energy due to a stretch or compression
Work: A force applied through a distance that changes the energy of the system Power: The rate of doing work
Hooke’s law: The force due to a stretch or compression.
Period of a pendulum Period of a mass on a spring The period is the inverse of the frequency
Gravitational Force: The force between two masses Gravitational potential energy: The potential energy between two masses
Coulomb’s Law: The force between two point charges.
The Electric Field: The force per unit charge at a point in space due to a the distribution of charges.
The Electric Potential (Voltage): The electrical potential energy per unit charge at a position in an electric field.
Capacitance: Charge stored on two parallel metal plates due to a potential difference between the plates. The capacitance is directly proportional to the Area of the plates and inversely proportional to the distance between the plates.
The resistance of a wire is directly proportional to the resistivity and length of the wire and inversely proportional to the cross sectional area.
Ohm’s Law: The relationship between the voltage, current and resistance. Current is directly proportional to the voltage and inversely proportional to the resistance.
As resistors are added in series the total resistance goes up. As resistors are added in parallel the total resistance goes down.
The magnetic force on a current carrying wire in a magnetic field
