Basic Physics
A quantity that has magnitude and direction
What is a vector?
The distance in a specific direction from a point
What is displacement?
What is momentum?
The energy an object has due to its velocity
What is kinetic energy
The unit for electrical current
What is Amperes, Amps
A quantity that has magnitude only
What is a scalar
The rate of change of distance or change of distance divided by time
What is speed?
What is Newton's 2nd law
The energy an object has do to work on a mass that is stored because of its height in a gravitational field
What is gravitational potential energy
The unit for voltage
What is Volts
How close a measured value is to the true value
What is accuracy?
The rate of chance of displacement
What is velocity?
The point where all the weight of an object is taken to act
What is the center of gravity (or center of mass)?
What is work
The units for electrical charge
What is Coulombs, C
The size of the smallest division on a measuring instrument
What is precision?
The rate of change of velocity
What is acceleration
The force multiplied by the perpendicular distance of action to the force to/from a point
What is the moment of a force?
The ratio of useful energy output from the system to the total energy input
What is efficiency
The units for resistance
What is ohms
Units that are created by multiplying or dividing base units together
What are derived units?
This is found by finding the area under the curve of a velocity vs time graph
What is displacement?
This principle states that for a body in rotational equilibrium, the sum of clockwise moments equals the sum of anticlockwise moments
What is the principle of moments?
Work done per unit time
What is power
The units for resisivity
What is Ohm-meter
