What is kinetic energy?
the energy an object has because of its motion.
What type of wave is energy?
electromagnetic waves
What is matter?
anything that has mass and takes up space
What is an atom?
the basic unit of an element
What is motion
occurs when there is a change in position of an object with respect to a reference point
What are 4 examples of kinetic energy?

What two factors affect kinetic energy?
mass and speed
What are 3 things that cause waves?

What are the properties of matter?
matter takes up space and matter has mass which gives it inertia
What is atom made of?
a central nucleus that is surrounded by one or more negatively charged electrons
What are Newton's laws of motion
An object in motion stays in motion unless an unbalanced force acts upon it.
What are 3 example sources of kinetic?
