Measure Twice, Answer Once!
This is the internationally accepted system of units for measurements in the scientific and medical fields.
The SI System
Equal to about 9.81 m/s/s near the surface of the Earth, this force is responsible for keeping us on the ground, as well as holding the solar system and galaxy together.
Gravity
Kinetic energy, the energy of motion, is dependent upon what two measurable quantities?
Mass and Velocity
Waves with the lowest frequencies and longest wavelengths on the electromagnetic spectrum are known as ______________.
Radio Waves (AM and FM)
A buildup of electric charges within a substance causes this form of electricity to be stored within the substance.
Static Electricity
Report this number of significant figures for area when multiplying a length of 3.2 cm and a width of 22.42 cm.
Two
Newton's 1st Law of Motion, also known as the Law of ____________, states that an object will continue its motion (or lack of motion) unless acted upon by an outside force.
Inertia
As object A is moved farther away from object B, object A's gravitational potential energy (increases or decreases) relative to object B?
Increases
Mechanical waves differ from electromagnetic waves in that they require a ______________ through which to travel.
A Medium
Watt
True or False? A collection of measurements may be precise, but also inaccurate at the same time.
True
This resistive force to motion is always directed in the opposite direction to an objects motion, and depends on the surface on which the object moves, as well as if the object is sliding or rolling.
Friction
In classical physics, this law explains why the total net energy of the universe must always be the same and equal to zero.
Conservation of Energy
Light is actually a combination of these two simultaneously oscillating waves moving together.
Electric and Magnetic
True or False? In the presence of an electrical potential difference, electrons will flow from an area of higher electrical potential to an area of lower electrical potential.
True
This commonly used method of number-reporting must be used in order to properly report significant figures when multiplying 12 and 25.
Scientific Notation
When an object is launched horizontally or at an angle, and the only force acting upon the object is gravity, the object is said to be in this type of motion.
Projectile Motion
Thermal energy, or heat, may be transferred by what three methods.
Convection, Conduction, and Radiation
True or False? The linear velocity of a mechanical wave remains unchanged when it travels from one substance into another. (ex. from air into water)
False
When an electric current enters fan and experiences resistance, electrical energy is converted into this other form of energy.
Mechanical Energy
State the standard metric units for each of the following physical properties: mass, time, temperature, electric current, amount of a substance, luminous intensity, and distance.
Kilogram, Second, Kelvin, Ampere, Mole, Candela, and Meter
A 2.0 kg object sliding down a frictionless inclined plane at 35 degrees above the horizontal will accelerate at this rate. (Assume this happens on the Earth's surface)
5.6 m/s/s
True or False: A line plot of temperature vs. thermal energy for water being heated from -10 degrees Celsius to 110 degrees Celsius would have a constant positive slope.
False
An observed "red shift" in wavelengths from objects in the distant universe due to this effect proves that the universe is, in fact, continuing to expand.
The Doppler Effect
A 100.0 watt light bulb connected to a 120 volt power outlet would have this amount of electrical current passing through it.
0.83 Amperes
