Motion Basics
This science studies matter, energy and how they work.
What is physics?
a push or a pull can make an object do this
what is start moving?
this force pulls object toward each other
what is gravity?
in science, work happens when a force does this to an object
what is move it?
this is a tool that makes work easier
what is a simple machine?
Newton explained this many laws of motion.
That is three.
This is an object's tendency to resist a change in motion
what is inertia?
when a ball is dropped on Earth, this force pulls it toward the ground
what is gravity?
this is the unit used to measure work
what is a joule?
this is a the number of simple machines
what are six?
This describes how far an object travels.
What is distance?
Newton's Third Law says every action has this
what is an equal and opposite reaction?
this force is air pushing against an object as it moves
what is air resistance?
this describes how quickly work is done
what is power?
this simple machine is a ramp
what is an inclined plane?
This kind of measurement tells size only, without direction.
What is a scalar quantity?
according to Newton's Second Law, using more force on an object can make it do this more
what is speed up?
this force can slow or stop motion
what is friction?
these two quantities are used to find momentum
what are mass and velocity?
this simple machine uses a wheel on a rope
what is a pulley?
This example gives both a distance and a direction: 5 meters to the right.
What is a vector?
the property that describes resistance to a change in motion is the clue to this concept
what is inertia?
these are the two main types of friction
what are static and kinetic friction
if two objects move at the same speed, a feather and a heavy truck, the truck has more of this?
what is momentum?
this simple machine is used to split wood
what is a wedge?
