|
The rate of change of velocity with time.
force/mass |
What is acceleration?
|
|
|
When two equal forces are applied on an object pushing both ways.
|
What is a balanced force?
|
|
|
The potential of a chemical substance to undergo a transformation through a chemical reaction or, to transform other chemical substances.
|
What is chemical energy?
|
|
|
Energy that never goes away.
It keeps transferring in a cycle. |
What is conservation of energy?
|
|
|
A form of energy that is reflected or emitted from objects in the form of electrical and magnetic waves that can travel through space.
|
What is electromagnetic energy?
|
|
|
The capacity to do work.
|
What is energy?
|
|
|
Any influence that causes an object to undergo a change in speed, a change in direction, or a change in shape
acceleration * mass |
What is force?
|
|
|
The force resisting the relative motion of solid surfaces, fluid layers, and/or material elements sliding against each other.
|
What is friction?
|
|
|
A natural phenomenon by which physical bodies attract with a force proportional to their mass.
|
What is gravity?
|
|
|
The tendency of an object to resist any change in its motion.
|
What is inertia?
|
|
|
Energy in motion
½ mass * volume squared |
What is kinetic energy?
|
|
|
It generalizes a body of observations. It explains things but it does not describe them.
|
What is law?
|
|
|
The amount of matter in an object.
|
What is mass?
|
|
|
The amount of work due to the combination of potential and kinetic energy.
|
What is mechanical energy?
|
|
|
The overall force acting on an object when all the individual forces acting on the object are added together.
|
What is net force?
|
|
|
The SI unit of force.
|
What is a Newton (as a unit)?
|
|
|
Energy of position, shape, or condition.
mgh m is the mass of the object, g is the acceleration due to gravity, and h is the altitude of the object |
What is potential energy?
|
|
|
The ratio of the change in y over the change in x.
Represents speed. |
What is the slope of a line?
|
|
|
Radiant light and heat from the sun.
|
What is solar energy?
|
|
|
The energy produced by sound vibrations. Usually measured in pressure and intensity.
|
What is sound energy?
|
|
|
How fast you are going.
distance/time |
What is speed?
|
|
|
A set of connected things working together to form a complex whole or network.
|
What is a system?
|
|
|
Summarizes a group of hypotheses or a single hypothesis.
It cannot be proven. |
What is a theory?
|
|
|
The kinetic energy of the movement of atoms and molecules.
heat |
What is thermal energy?
|
|
|
Energy is transferred from one type to another and then back again.
|
What is transfer (energy)?
|
|
|
When the energy changes into another form.
|
What is transform (energy)?
|
|
|
Force that produce a non-zero net force which changes an object's motion.
|
What is an unbalanced force?
|
|
|
A way of creating heat through the fission process of atoms.
Fission is a splitting of something into two parts. |
What is nuclear energy?
|
|
|
Transfer of energy to an object with a force that causes the object to move.
force * distance |
What is work?
|
|
|
mass * velocity
The quantity of motion of a moving body. |
What is momentum?
|
|
|
Speed in a given direction.
momentum/mass |
What is velocity?
|
|
|
An object in motion stays in motion unless a force acts upon it. An object at rest stays at rest unless a force acts upon it.
|
What is Newton's 1st law?
|
|
|
The acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.
|
What is Newton's 2nd Law?
|
|
|
For every action, there is an equal and opposite reaction.
|
What is Newton's 3rd law?
|
