The rate at which velocity changes over time.
Acceleration
A measure of how fast something moves through a particular distance over a definite time period. speed is distance divided by time.
Speed
A speed in a specific direction.
Velocity
A force that resists the motion between two surfaces in contact.
Friction
A measure of how much matter an object is made of.
Mass
The force of gravity on an object.
Weight
A push or a pull; something that changes the motion of an object.
Force
The force that objects exert on each other because of their masses.
Gravity
A change of position over time.
Motion
The rate at which work is done.
Power
The use of force to move an object over a distance.
Work
A substance that cannot be broken down into a simpler substance by ordinary chemical changes. An element consists of atoms of only one type.
Element
The energy of motion. A moving object has the most kinetic energy at the point where it moves the fastest.
Kinetic energy
Stored energy; the energy an object has due to its position, molecular arrangement, or chemical composition.
Potential energy
A law stating that no matter how energy is transferred or transformed, all of the energy is still present in one form or another.
law of conservation of energy
