D1 motion
What is 1D motion?
Its a movement along a straight line
Kinematics?
Motions of bodies, points, and systems of bodies without considering the forces that caused them to move
Force?
Action that can change motion
What is mass?
Amount of matter in object.
Friction?
Force that opposes motion between 2 forces
Velocity
Speed with direction
Units for speed
M/s = speed
Force equation
F=ma
What is weight
Force of gravity on objects mass
What is newtons 3rd law?
For every action force there must be a reaction force that is equal in strength and opposite in direction
How to find speed?
Distance/time
Big 4
X=Xo+Vot
V=Vo+at
X=Xo+Vot+at²1/2
V=V²o+atdeltax
Mass equation
M=f/a
What is density?
Amount of mass in volume
Newtons second law?
The acceleration of an object is directly proportional to the magnitud of the net force
How to find slope
Pick 2 points and plug it into gx=y2-y1/x2-y1
Distance?
Length of time traveled
Accusation equation
A=f/m
How to find density?
q=m/v
How to find weight
W=Mg
Acceleration?
Speeding up or slowing down in a direction
Displacement
Shortest distance between 2 points
Weight of gravity?
9.8
What is net force
Sum of all forces acting on object
What force does everything have
Gravity
