Definitions
the ability to cause change or to do work
What is energy?
energy of heat through contact, like a hot grill or stove
What is thermal energy?
An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force. (Inertia)
What is Newton’s First Law of Motion?
is a force that opposes motion
What is friction?
a vibration that travels through a material, such as air or water
What is sound energy?
an object’s direction and speed
What is motion?
energy associated with flowing electrons, like static electricity or current electricity
What is electrical energy?
A ball will stay still until a force acts upon it
What is Newton’s First Law of Motion?
a push or a pull that causes an object to move, stop, or change speed or direction.
What is force?
electromagnetic energy that people can see
What is light energy?
push or a pull that causes an object to move, stop, or change speed or direction.
What is force?
energy an object has due to its motion and position, like wind power or sound
What is mechanical energy?
The acceleration of an object depends on the mass of the object and the amount of force applied. (Force)
What is Newton’s Second Law of Motion?
it creates heat
What is friction?
how fast an object is moving
What is speed?
the energy of motion
What is kinetic energy?
stored energy
What is potential energy?
Whenever one object applies a force on a second object, the second object applies an equal and opposite force on the first. (Action and Reaction)
What is Newton’s Third Law of Motion?
related to net force and mass
What is motion?
a microwave does this energy transformation
What is electrical energy to thermal energy?
the combination of all forces acting on an object
What is net force?
energy that travels in waves, like sunlight, microwaves, or X-rays
What is radiant energy?
the reason we can jump up
What is Newton’s Third Law of Motion?
energy is transferred from one object to another
What is a collision?
a solar calculator does this energy transformation
What is radiant energy to mechanical energy?
