distance from another object changes, change in position
place or object used for comparison
the time it takes something to move a distance
speed and direction
size/magnitude and direction
a speed that stays the same through the distance
speed at any instant
the length of all parts/between two points
the distance from start to end, the overall change in position and a direction
the rate at which velocity changes
all the forces of an object balance out
the property of an object that it resists to change in motion
amount of matter in an object
mass in motion
-a push or a pull
-results in two or more objects interacting with each other
-all forces have magnitude and direction
-measured in Newtons (N)
-increase speed: speed up
-decrease speed: slow down, deceleration
Speed (distance-time) graphs
-point on graph= location of an object from 0 at a particular time
-straight slope=constant speed
-horizontal line=no movement
-point on graph=speed of object at a particular time
-straight line=constant acceleration
-steeper slope=greater acceleration
-horizontal line=constant speed
distance / time
speed x time
distance / speed
total distance / total time
final velocity - initial velocity/time
force / acceleration
mass x acceleration
force / mass
mass x velocity
Newton's Laws of Motion
An object at rest will stay rest, and an object in motion will stay in motion until a force acts on it.
Force causes acceleration, while mass resists acceleration.
Any action has an equal and opposite reaction.
Types of Forces
a force exerted by physically touching
a force applied by a person/object to change another object's motion
a force exerted by a surface on an object resting on it
one surface exerts another when in contact, acts in opposite direction to the object's motion
a force that acts without physically touching
a natural force that pulls objects toward the center of the earth
materials with magnetic fields that attract/repel other objects
the force of two charged objects attracting/repelling each other
force that keeps objects moving in a circular path, "center-seeking"
perception of being pushed outward, "false force"
