1.
change in an object’s motion (speed and / or direction); caused by unbalanced forces; measured in m/s2
2.
measure of the size of the disturbance of a wave; height on the y-axis
3.
force that is applied on an object by a person or another object
4.
total distance an object traveled by the total time it has traveled
5.
equal and opposite forces on an object that result in no change in position, direction, or motion; combined net force equals zero
6.
the transfer of thermal energy between objects in direct contact with each other
7.
the transfer of thermal energy through currents in liquids and gases
8.
how far an object has moved from its original position; the difference between the final and initial positions
9.
the process of energy changing from one form to another
10.
energy is taken from one place to another (e.g., in a food web, energy is transferred from producer to consumer)
11.
a push or pull acting on an object
12.
the number of times a wave passes a certain point in a given amount of time
13.
a force that acts in the opposite direction to movement
14.
a force that pulls objects toward each other\
15.
energy travels in the same direction (parallel) as the vibrations of the medium particles
16.
a force that pushes or pulls a magnetic material across a distance
17.
a measure of the amount of matter in a sample
18.
an object changes its position
19.
measurement of the total forces exerted on an object, measured in Newtons (N)
20.
the tendency of an object to resist change in motion unless acted upon by an outside net force
21.
when an object that has a constant mass is acted upon by a force, the object will accelerate in the same direction as the force applied
22.
for every action, there is an equal and opposite reaction
23.
the transfer of thermal energy from a light source (e.g., Sun, fire, light bulb, and burner) to an object or a substance
24.
unequal forces acting on an object that may result in a change in position, direction, or motion; combined net force does not equal zero (greater than zero)
26.
a movement of energy through a medium or space from one place to another
27.
the linear distance between identical points on successive waves
