Scientific Method & Units
a systematic, empirical process used to explore observations, test ideas, and answer questions about the natural world
The Scientific Method
This term describes both the distance and direction of an object's position relative to a starting point
Displacement/Distance
Newton's First Law of Motion is also widely known as the Law of this
Bill Nye says: "It's as property of matter" :)
Inertia
Energy stored in chemical bonds, such as calories in milk or food, is known as this form of potential energy
Chemical Potential Energy
The accumulation of excess electric charges on an object's surface
Static
This factor in an experiment is adjusted or changed by the experimenter and is plotted on the x-axis
Independent Variable
Velocity differs from speed because velocity explicitly includes this
Direction
These microscopic surface bumps cause resistance when two surfaces touch, resulting in friction
Microwelds
The standard SI metric unit used to measure work and energy
Joules
A material through which electrical charges or electrons cannot move easily
Insulator
This standard metric SI base unit is used for measuring temperature
Kelvin
The slope of a distance-versus-time graph represents this quantity
Speed or Velocity
This type of friction opposes the motion of a skateboard or bicycle wheel moving across a flat floor
Rolling Friction
Performing 900 Joules of work over a duration of 5 seconds equals this amount of power
180 Watts
This standard unit is used to measure electrical resistance
Ohm
This physical quantity is defined as mass per unit volume (m/V)
Density
If an airplane accelerates from 0m/s to 80m/s in 20 seconds, its acceleration rate is....
4 m/s2
According to Newton's Second Law, Force (F) equals mass (m) multiplied by this (a)
A lever class that has the fulcrum located directly between the input force and output force
1st Class lever
A group of atoms with aligned magnetic poles inside a magnetic material
Magnetic domain
Give the steps of the scientific method in order. (there are 8)
Ask a question, research, hypothesis, experiment, gather and analyze data, conclusion, share results, further research
This center-seeking acceleration causes an object to move in a curved or circular path
Centripetal Acceleration
The momentum (p) equation shows that momentum is calculated by multiplying mass (m) by this
Velocity
This simple machine consists of an inclined plane wrapped in a spiral around a central post
Screw
Electric current that flows continuously in only one direction
Direct current or Series Circuit
