# Laws of Motion

TermDefinition
First Law of Motion Objects at rest remain at rest and objects in motion continue at a constant velocity unless acted upon by an unbalanced force.
Inertia The tendency of an object to not change its motion.
Second Law of Motion acceleration = force / mass
Gravity The force of attraction between all objects that depends on the mass of the objects and the distance between them.
Weight The force due to gravity.
Centripetal Force The force that causes objects to move in a curved or circular path.
Centripetal Acceleration The acceleration of an object because it is moving in a curved or circular path.
Third Law of Motion For every action force there is an equal and opposite reaction force.
Momentum The property of a moving object that is the product of its mass and velocity.
Law of Conservation of Momentum States that the total momentum of objects remains the same.
Newton SI unit of force
Kilogram SI unit of mass
m/s/s SI unit of acceleration
9.8m/s/s The acceleration due to gravity of objects near Earth's surface (neglecting air resistance).
