Newton Unit

Newton's First Law

"An object at rest will remain at rest, and an object moving at a constant velocity will continue moving at a constant velocity, unless it is acted upon by an unbalanced force." Another name is Law of Inertia

Gravitational Acceleration

9.8 m/s/s

Centripetal Force

A force that causes an object to move in a circle

Momentum

A quantity defined as the product of the mass and velocity of an object Momentum=Mass*Velocity

Newton

A unit of measure that equals the force required to accelerate 1 kilogram of mass at 1 meter per second per second

Inertia

An objects resistance to change its motion

Balanced Force

Equal forces acting on an object in opposite directions

Newton's Third Law of Motion

For every action there is an equal and opposite reaction

Newton's Second Law of Motion

Relationship between force, mass, and acceleration Force= mass*acceleration

Net Force

The combination of all forces acting on an object

Terminal Velocity

The constant velocity of a falling object when the force of air resistance is equal in magnitude and opposite in direction to the force of gravity

Projectile Motion

The curved path an object follows when thrown or propelled near the surface of the Earth.

Free Fall

The motion of a falling object when the only force acting on it is gravity

Law of Conservation of Momentum

Total momentum of a system of objects does not change as long as no outside forces are acting on that system

Unbalanced Force

Unequal forces acting in the same or opposite direction

Action and Reaction pair

if a force is exerted, another force occurs that is equal in size and opposite in direction , what are these called?
