Acceleration

Acceleration

The rate at which an object changes speed or direction

Balanced Force

when two or more forces act upon an object so as to exactly counteract each other

Unbalanced Force

is a force that changes the position, speed or direction of the object to which it is applied

Centripetal force

is a force that pushes an object in an inward direction

Centrifugal Force

is a force that pushes an object in an outward direction

Energy

the ability to do work

Force

is a push or a pull acting upon an object

Friction

is a force that resists the motion of an object

G

is a unit of acceleration equal to the acceleration caused by gravity

Gravity

Any two objects with mass attract each other

Inertia

is a tendency of an object to resist change in its state of motion

Kinetic Energy

is the energy possessed by an object because of its motion

Mass

is a measurement of the amount of material in a object

Momentum

pertains to the quantity of motion that an object possesses

Period

motion that repeats itself in cyclic fashion

Potential Energy

is the energy possessed by an object because of its height above the ground

Speed

is a measurement of how fast an object is moving

Velocity

refers to the speed and direction in which an object moves

Weight

is a measurement of the gravitational force acting on an object

Weightlessness

is a sensation in which a person no longer feels an external force acting upon their bodies

Work

measure of energy transfer that occurs when an object is moved over a distance by an external force

Newton's First Law of Motion

an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force

Newton's Second Law of Motion

the greater the mass of an object, the more force it will take to accelerate the object

Newton's Third Law of Motion

for every action, there is an equal and opposite reaction
