If the net force acting on an object is zero, the object remains at rest, or if the object is already moving, continues to move in a straight line with constant speed.
What is Newton`s First Law
100
The acceleration of an object equals the net force divided by the mass and is in the direction of the net force.
What is Newton`s Second Law
100
Forces always act in equal but opposite pairs.
What is Newton`s Third Law
100
The combination of all the forces acting on an object.
What is Net Force

What is my middle name?
What is Jean
500

What is Center of Mass
500
When air resistance balances the force of gravity, the object falls at a constant speed
What is Terminal Velocity
500
When an object moves in circular motion, the net force on the object
What is Centripetal Force
500
Pulling you downward. Gravity also is the force that causes Earth to orbit the Sun and the Moon to orbit Earth
