Classical Physics Flashcards
Speed (p. 16)
A measure of how fast something moves in a particular distance over a definite time period. Speed is the distance divided by time.
Acceleration (p. 25)
The rate at which velocity changes over time
Velocity (p. 22)
A speed in a certain direction
Friction (p. 85)
A force that resists the motion between two surfaces in contact.
Mass (p. XV)
A measure of how much matter an object is made of
Weight (p. 79)
The force of gravity on an object
Force (p. 41)
A push or pull something that changes the motion of an object
Gravity (p. 77)
The force that object exert on each other because of their masses
Motion (p. 11)
A change in position over time
Power (p. 130)
The rate at which work is done
Work (p. 115)
The use of force to move an object over a distance
Energy (p. XIX)
The ability to do work or cause a change. For example, the energy of a moving bowling ball knocks over pins; energy from food allows animals to move and grow; and energy from the sun heats earths surface and atmosphere, which causes air to move.
Kinetic energy (p. 122)
The energy of motion. A moving object has most KE at the point where it moves the fastest.
Potential energy (p. 122)
Stored energy; the energy an object has due to its position, molecular arrangement, or chemical composition.
Law of Conservation of Energy (p. 126)
A law stating that no matter how energy is transferred or transformed, all of the energy is still present in one form or another.
