States that if the net force acting on an object is zero, the remain at rest or move in a straight line with constant speed
What is Newton 1st law

The weight of an object is the size of the gravitational force exerted on an object.
What is WEIGHT
100
a property of matter by which it continues in its existing state of rest
What is INERTIA

Newton’s second law of motion, 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 2nd law
200
a number expressing a relation or property that remains the same in all circumstances, or for the same substance under the same conditions.
What is CONSTANT

sliding friction acts in the direction opposite to the motion of the box. If you stop pushing, sliding friction causes the box to stop.
What is SLIDING FRICTION

The center of mass is the point in an object that moves as if all the object’s mass were concentrated at that point
What is CENTER OF MASS

Newton’s third law of motion, forces always act in equal but opposite pairs.
What is Newton 3rd law
300
the speed and direction of a moving object
What is VELOCITY
300
Rolling friction occurs when an object rolls across a surface. It is rolling friction between the bicycle tires and the ground
What is ROLLING FRICTION
300
When air resistance balances the force of gravity, the object falls at a con- stant speed called the terminal velocity.
What is TERMINAL VELOCITY
400
The com-bination of all the forces acting on an object
What is Net Force
400
Two or more forces exerted on an object are balanced forces if their effects cancel each other and they do not change the object’s velocity.
What is BALANCED FORCES
400
Static friction is caused by the attraction between the atoms on the two surfaces that are in contact. This causes the surfaces to stick or weld together where they are in contact.
What is STAIC FRICTION
400
The direction of the centripetal force is toward the center of the object’s circular path.
What is CENTRIPETAL FORCE

The force that brings nearly everything to a stop is friction, which is the force that acts to resist sliding between two touch- ing surfaces
What is FRICTION
500
If the net force is not zero, the forces are unbalanced forces.
What is UNBALANCE FORCES
500
The force of gravity exists between any two objects that have mass. Gravity always is attractive and pulls objects toward each other
What is GRAVITY
500
The direction of the centripetal force is toward the center of the object’s circular path.
