Kinetic and Potential energy
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?
A person walking, a soaring baseball, a crumb falling from a table and a charged particle in an electric field
What is an example of energy in waves?
Sound waves carry noises through the air to our ears
What are the states of matter?
solid, liquid, and gas
What are the 5 parts of an atom?
protons, electrons, and neutrons
What is in motion and not in motion?
running, cycling, jumping, swimming and moving car
What two factors affect kinetic energy?
mass and speed
What are 3 things that cause waves?
water's motion, gravitational forces, and winds
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?
running, cycling, climbing
What determines energy of a wave?
their frequency and their amplitude.
What is matter made of?
tiny particles called atoms and molecules
What do atoms do?
basic building blocks of ordinary matter
What are 4 characteristics of motion?
distance, displacement, speed, and time
What are the two main forms of energy?
Potential energy and Kinetic energy
What are the 3 main types of waves?
Mechanical waves, Electromagnetic waves, Matter waves
Why is heat not a matter?
do not have measurable mass and can't be contained in a volume.
What are the 4 types of atoms?
hydrogen atoms, helium atoms, carbon atoms, oxygen atoms
What type of force has no motion?
Balanced forces
