Laws of Motion

TermDefinition
Force of Gravity a force that PULLS every object toward the center of the Earth
Weight the measure of how hard gravity pulls an object
Magnetic Forces the force between two magnets or between a magnet and certain metals such as iron that can push back
Electrostatic Forces This force has to do with the charge an object carries.
Mechanical Forces This is a push or pull that one thing exerts on a system's state of rest or uniform motion
Friction This is a force that slows things down
Spring Force When an object changes shape when a force is applied to them.
Newton's First Law of Motion Things do not change their motion unless a force acts on them.
Balanced Force separate forces that combine to cancel each other out to make a net force of zero
Unbalance Force a force that is not cancelled out by another force
Newton's Second Law of Motion When a force continues to act on an object, it will continue to move - unless acted upon by another force.
Potential Energy stored energy
Kinetic Energy the energy of motion
Acceleration increasing speed
Negative Acceleration a force causing a moving object to slow down
Newton's Third Law of Motion for every action there is an equal and opposite reaction
Force a push or pull that causes an object to move, stop, or change direction
Motion describes change in an object's position with respect to time and in comparison to other objects
