1st law
(law of inertia)
An objects motion remains until acted upon by another unbalanced force
Inertia
The resistance to any change in motion
Mass
Amount of matter in an object
Weight
Force of gravity pulling on an object (on earth its 9.8 m/s/s)
2nd law
Force
A force is a push or a pull on an object that can change its motion, speed, direction, or shape
Unbalanced force
a net force acting on an object that is not equal and opposite, meaning the forces do not cancel each other out
Newtons third law
for every action, there is an equal and opposite reaction, meaning that forces always exist in pairs.
Action force
the initial force applied by one object on another, which is always paired with an equal an opposite reaction force
Reaction force
the equal and opposite force that an object exerts back on another object when a force is applied
Energy
ability to work or cause change
Energy transfer
The movement of energy from one object or system to another
Energy transformation
The change of energy from one form to another
Kinetic energy
the energy of motion, meaning it is the energy an object possesses because it is moving
Potential energy
energy stored in an object due to its configuration, state or position
Types of kinetic energy
Mechanical, electric, thermal, sound, light
Types of potential energy
chemical, elastic, nuclear, gravitational
Balanced force
two or more opposing forces acting on object, resulting in a net force of zero and no change in the object’s motion
Speed
the rate at which someone or something moves or operates or is able to move or operate.
Velocity
the speed of something in a given direction.
Distance
the length of the space between two points.
Displacement
Change in an objects positon in a straight line
Acceleration
the rate at which an object’s velocity changes over time
Deceleration
Reduction in speed or rate
