This describes how far an object moves during a certain amount of time.
________ = Distance/Time
What is AVERAGE SPEED?
100
This number is divisible by 12. The number of laws of motion Sir Isaac Newton developed.
What is 3?
100
Hey, why aren't you doing this in class?? It might help if you PICK UP your pencil! This is done when a force moves an object.
What is WORK?
100
You use one when you try to use chop sticks when eating Chinese food. Even your toothbrush is one of these. These devices make work easier.
What are SIMPLE MACHINES?
100
This force pushes and pulls, holds you down on the ground, and does NOT exist in space.
What is GRAVITY?
200
This is the set location against which motion is measured. It's also known as a starting point.
What is a POINT OF REFERENCE?
200
Go this way! No, go this way! Hey, slow down! No, speed up!
This is the rate at which the velocity of an object changes. It is also Newton's Second Law of Motion.
What is ACCELERATION?
200
Wow! That was done pretty fast!! Maybe you need to slow down! This is the rate at which work is done.
What is POWER?
200
An electric drill, a car, a bus, a bicycle. These are devices that change the direction or the amount of force needed to cause an object to move.
What is a MACHINE?
200
This is the amount of gravitational pull the Earth has on an object! If you were on the moon, it would be ZERO!
What is WEIGHT or MASS?
300
Which way did it go?? That was fast!! This describes BOTH the speed and direction of an object's motion.
What is VELOCITY?
300
Hey! Stop being so PUSHY!! Don't PULL on that!
Newton's Third Law of Motion states when one object exerts a force on a second object, the second objects exerts an equal force on the first object.
What is THE ACTION-REACTION LAW OF MOTION or EQUAL-OPPOSITE FORCES?
300
Oh No! Math in Science!! UGH! This is the formula used to calculate the amount of power being exerted during work.
What is POWER = WORK / TIME?
300
This simple machine can be found in your grandmother's back yard, attached to 2 trees. It consists of a rope or cable that runs through a grooved wheel. It changes the direction of the force needed to move an object.
What is a PULLEY?
300
This force pushes and pulls on objects. It's force is the strongest at its poles.
What is MAGNETISM?
400
This concept does NOT include the direction in which an object moves. It DOES include how fast or slow an object is moving.
What is SPEED?
400
Zoom! There it goes!! Uh, hello? Why it isn't moving?
Newton's First Law of Motion states unless this acts on an object, the object will remain in constant motion. An object at rest will remain at rest until acted upon by this as well.
What is a NET FORCE?
400
Work, work, work, work, work! Busy, busy, busy! The unit in which work is measured.
What are JOULES?
400
This simple machine is a favorite mode of transportation among children. This part of it is made up of a circular object and a chain. A doorknob is another example of one of these.
What is a WHEEL & AXLE?
400
This happens when objects gain or lose electrons. Watch out or it'll ZAP you!!
What is ELECTRICITY?
500
How much force is there? These are the units in which the magnitude of force is measured.
What are NEWTONS?
500
Why won't that rock move? Man, that's stubborn! This is the tendency for an object to resist any change in motion.
What is INERTIA?
500
Heave! Ho! Heave! Ho! Use those muscles and make it go! We have to make it all the way to the other side of the street! The formula for calculating the amount of work being done when a force acts on an object.
What is WORK = FORCE X DISTANCE?
500
This simple machine can be found in playgrounds. It's made up of a stiff bar that rotates around a fixed point called a fulcrum. The further away the force is from the fulcrum, the easier this is to use.
What is a LEVER?
500
Work, work, work, work, work!! Ouch! This occurs when two objects rub together in opposite directions. It creates heat and static electricity.
