Lets move
A push or pull that causes an object to have a change in movement or direction
What is FORCE

4)Wheel and Axle 5) Pulley 6)Screw
The rate at which an object travels in a certain amount of time
What is SPEED
The ability to do work
What is ENERGY
A human arm can be an example of
What is a 3rd Class Lever
The change in position of an object
What is MOTION
A wheelbarrow is an example of this type of lever
2nd Class Lever
The speed of an object at a specific instant in time
What is INSTANTANEOUS SPEED
Energy in motion
What is Kinetic Energy
The fulcrum is in the center of a
1st Class Lever
The resistance to motion when two objects rub against one another
What is FRICTION
Makes “WORK” easier by changing the direction of force being used
A Pulley
The speed and direction of an object
What is VELOCITY
Energy that exists but is not being used
What is POTENTIAL ENERGY

Compound.
What are 3 types of pulleys?
How much ground has been covered during the movement of an object
What is DISTANCE
An inclined plane wrapped around a rod
What is a screw?
Any change in direction and/or speed, either faster or slower
What is ACCELERATION
Energy cannot be created or destroyed but can change from one form to another
What is CONSERVATION OF ENERGY
Zip lining uses these kinds of
Simple Machines
Moveable Pulley
The measure of how much matter is in an object; objects with greater mass feel heavier; and objects with less mass feel lighter regardless of size
What is MASS
The first invention that was not inspired by something already existing in nature.
The Wheel and Axle
Newton’s Second Law as an equation
What is F=ma
(force = mass X acceleration)Energy resources that are reusable and sustainable because they never run out, that are sourced from the earth, and that do not emit harmful byproducts into the earth’s environment
What is RENEWABLE ENERGY
