Term
 Physics
Definition
 The study of matter and energy and their relationships
Term
 The unit of work
Definition
 Joule
Term
 If you were to lift two equally heavy loads of laundry up a flight of stairs, how much work do you do compared to lifting just one load of laundry up two flights of stairs?
Definition
 The same
Term
 The unit of power
Definition
 Watt
Term
 The unit of energy
Definition
 Joule
Term
 Potential energy is the energy an object has because of its...
Definition
 position or location
Term
 Vector
Definition
 A quantity that has Magnitude and Direction
Term
 What are 3 possible units for speed?
Definition
 Miles per hour, light years per century, kilometer per hour
Term
 In the absence of air resistance, objects fall at a constant _______
Definition
 acceleration
Term
 What is an objects instantaneous speed at the top of a vertical projectile's path?
Definition
 0 m/s
Term
 How fast does a free falling object fall after 9 seconds?
Definition
 90 m/s
Term
 If you drop a hammer and a piece of paper in a vacuum, which will hit the ground first?
Definition
 Both will both hit it at the same time
Term
 The Law of Inertia
Definition
 An objects tendency to stay in motion or at rest
Term
 T or F: An object on Earth will weigh less on the Moon
Definition
 True. Mass or Volume would say the same
Term
 T or F: Friction always works against an objects motion
Definition
 True
Term
 An object that is going in a straight line and has a constant speed has zero _______
Definition
 acceleration
Term
 Newton's First Law
Definition
 An object in motion will stay in motion unless acted upon by an outside force. Also known as the Law of Inertia
Term
 Newton's Second Law
Definition
 Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).
Term
 Newton's Third Law
Definition
 For every action, there is an equal or opposite reaction
Term
 Chemistry
Definition
 The central science. The study of matter and their tranformations
Term
 South Pole of a magnet
Definition
 Magnetic field goes into this pole of a magnet.
Term
 North Pole of a magnet
Definition
 The magnetic field exits this pole of a magnet.
Term
 Volts
Definition
 Electrical unit to measure potential difference.
Term
 Amperes
Definition
 The electric unit to measure current.
Term
 Ohms
Definition
 The electrical unit to measure resistance.
Term
 Electric Circuit contains what four basic parts?
Definition
 A electrical unit that contains a battery (source), wires (path), load (light or resistor), and control(a switch).
Term
 Series circuit
Definition
 Electric circuit with only one path.
Term
 Parallel circuit
Definition
 An electric circuit with more than one path.
Term
 Ohm's Law
Definition
 V = I * R
Term
 Electric Power formula
Definition
 P = V * I
Term
 Kinematics
Definition
 The study of motion: position, speed, velocity, and acceleration.
Term
 Find the speed of a car if it travels 30 meters in 5 seconds
Definition
 6.0 m/s
Term
 Find the acceleration if the velocity changes from 20 m/s to 40 m/s in 2 seconds.
Definition
 10 m/s/s
Term
 An inclines plane has a rise or 2.0 meters and a run of 10 meters. What would be the theoretical acceleration down this incline without friction?
Definition
 a = 10 m/s/s * rise/runso a = 2 m/s/s
Term
 If a 200 g cardboard car were traveling down an incline with a rise of 2.0 meters and a run of 10 meters, and its acceleration is only 1.5 m/s/s, what would the frictional force experienced down the incline?
Definition
 2.0 m/s/s - 1.5 m/s/s gives a difference of 0.5 m/s/s reduction by friction therefore the frictional force must have been F = ma of .2 kg * 0.5 m/s/s or .010 N !
