Matter
matter that can keep its shape
solid
Forces that result in work are what kind of forces?
unbalanced
an objects acceleration is determined by the forces acting upon it as well as its mass
second law of motion
the pull of gravitational force exerted on an object by another object
weight
a neutral subatomic particle
neutron
empty space with no matter
vacuum
a pulling force created between a rope or cable and an object
tension force
total mass of substances stays the same before and after an interaction
law of conservation of mass
What type of acceleration is a change in motion to a slower rate?
negative acceleration
a heterogeneous mixture with tiny, suspended clumps or particles
colloid
movement of matter or a change in the position of matter
motion
a resisting force between 2 objects rubbing against one another
frictional force
energy can neither be created nor destroyed, only transferred
law of conservation of energy
an upward force exerted by a fluid on a solid object placed in the fluid
buoyancy
method used to separate solid materials from one another
skimming
push or pull on an object
force
What kind of force is thrust?
reaction force
speed and direction of an object does not change unless acted upon by unbalanced forces
first law of motion
change in speed, direction, or both
acceleration
a homogeneous mixture in which one kind of substance is dissolved into another
solution
the ability to do work and change matter
energy
2 opposite poles working differently to create a force field
polarity
for every action there is an equal and opposite reaction
third law of motion
distance traveled divided by a unit of time measures this
speed
2 or more kinds of substances that have been combined physically, but have not bonded chemically
mixture
