23 terms

acceleration

the rate at which velocity changes over time

average speed

the total distance traveled divided by the time it takes to travel that distance

balanced force

when two forces that are acting on an object are equal, but in opposite directions. Forces cancel out.

constant speed

speed that does not change over time

electrical force

force of attraction or repulsion of charged particles

Force

a push or pull exerted on an object

friction

the force that one substance exerts on another when the two rub against each other

gravitational force

the force created by gravity

Gravity

the force of attraction between all masses in the universe

horizontal

parallel to level ground, line side to side

Kinetic Energy

the energy an object has due to its motion

linear

a straight line

Motion

the state in which one object's distance from another is changing

net force

the overall force acting on an object

nonlinear

not a straight line, curved

Potential Energy

energy stored due to an object's position or arrangement

reference point

place or object used for comparison to determine if something is in motion

slope

the ratio of the change in the y-coordinates (rise) to the corresponding change in the x-coordinates (run) as you move from one point to another along a line, rise or run (steepness)

speed

the distance the object travels in one unit of time

unbalanced force

when the net force changes an objects motion

velocity

the speed of an object in a particular direction

vertical

perpendicularly to the horizon, line up and down

inertia

tendency of an object to resist a change in motion unless acted upon by an external force
