FORCES STUDY GUIDE

SCIENCE

friction

a force opposes the motion of another object; making the object slow down, or giving it traction to get moving

position

a comparison of an object's location on a map to other things on the map

gravity

the force that pulls down

mass

the measure of the amount of matter in an object

matter

Anything that has mass and takes up space

acceleration/force relationship

the more force you apply, the greater the acceleration

acceleration/mass relationship

the greater the mass, the more force necessary to get an object to accelerate

weight

is a measure of gravitational force between earth and an object

speed

distance over time

velocity

speed in a given direction

acceleration

change in speed or direction

balanced forces

do not change speed or direction

unbalanced forces

do change speed or direction

Inertia

resistance to change in motion

force

push or pull

Distance

The length of a path between two points
