Law of Inertia
Newton's 1st Law is also know as the law of:
inertia
_______ is the property of an object that leads it to resist any change in motion
Which Law:
Newton's First Law of Motion
F=m x a OR a=f/m
What is the equation for the relationship for acceleration to mass, and force?
mass
a body of coherent matter, usually of indefinite shape and often of considerable size
weight
A force that comes from gravity pulling down on any object with mass
friction
a contact force; type of force between two touching surfaces
acceleration
(physics) a rate of change of velocity
Velocity
a speed in a particular direction.
work = force x distance
What is the equation for Work when force and distance are known?
work
a force acting upon an object to cause a displacement. (key words: force, displacement, and cause)
Force = Work/Distance
What is the equation for Force when work and distance are known?
force
(interactions between two objects)
T = d/s
What is the equation for time when speed and distance are known?
d = xf - xi
What is the equation for distance when the initial position and final position are known?
V = d/t
What is the equation for speed when distance and time are known?
motion
An object is moving if its position relative to a fixed point is changing.
