18 terms · Gr 6 Force and Motion

a push or a pull

motion

a change in distance from another object

balanced forces

equal forces acting in opposite directions

friction

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

reference point

a place or object used for comparision in order to tell if an object is in motion

speed

the distance an object travels in one unit of time

velocity

speed in a given direction

unbalanced forces

a force that changes an object's motion

newton

SI (metric) unit of force

average speed

Total distance divided by total time

constant speed

object that is moving at the same rate because of equally applied forces

displacement

distance and direction of an object's change in position from the starting point

distance vs time graph

the purpose is to describe the motion of an object in relation to a fixed point at the start

position vs time graph

shows where an object it as a certain time

speed vs time graph

shows the speed of an object during a specific time

slope

the steepness of a line on a graph, rise over run

position

the particular portion of space occupied by a physical object

direction

a pathway that leads to the point of destination
