Position, Distance, and Displacement
The starting point
Reference point
Describes an object travelling at a constant speed in one direction
Uniform motion
The combination of all forces of an object
net force
A line segment that represents the size and direction of a quantity
Takes into account total distance and time of a trip
average speed
a unit of force
newton
Describes how much an objects position has changed
Displacement
A measure of steepness calculated by comparing the rise and run
slope
the resistance of an object to change in motion
inertia
Quantity that only involves size, no direction
Scalar
the change in velocity over a period of time; increase or decrease
acceleration
a force that occurs when surfaces slide over one another, reduces acceleration
friction
A change in position
Motion
is an attractive force between two objects that have mass. the object with more mass will pull the other object towards it
gravity
a diagram used to show the relative magnitude and direction of all forces acting upon an object in a given situation
free body diagram
