A
__________________ is the direction of a moving object
Velocity
A __________________ is a push or pull.
force
__________________ is the tendency of matter to resist a change in its state of motion.
inertia
__________________ are forces that cancel out one another
Balanced Forces
__________________ is a measure of the force of gravity on an object.
weight
__________________ is an object's change in velocity divided by the time it takes for that change to occur.
Acceleration
5. __________________ are forces that do not cancel out one another.
unbalanced forces
A __________________ is a force that acts between any two masses in the universe and pulls them toward each other.
gravitational force
Motion needs a __________________.
force
Newton's __________________ law of motion explains that an object's motion depends on its mass and the amount of force being used against that mass.
second
__________________ is an invisible force that slows down moving things.
Friction
In science, you do __________________ when you move something.
work
Newton's __________________ law says that an object at rest will remain at rest unless a force acts upon it.
first
_________________ is a force that can push or pull objects made of certain metals, such as iron.
Magnetism
Newton's __________________ law of motion says that for every force or action, there is an equal and opposite reaction.
third
. Newton's first law of motion is sometimes called the law of __________________.
inertia
Force X __________________=Work
Distance
__________________ energy is stored energy.
Potential
________________ energy is energy in motion.
Kinetic
Converting and moving energy is called __________________.
energy transfer
