Term
 Force
Definition
 any influence that tends to accelerate an object push or pull measured in Newtons
Term
 Equilibrium
Definition
 a state of balance the state of a body on which no net force acts
Term
 Friction
Definition
 the force that acts to resist the relative motion of objects or materials that are
Term
 Inertia
Definition
 the reluctance of any body to change its state of motion. Mass is the measure of inertia.
Term
 kilogram
Definition
 the fundamental SI unit of mass. One kilogram is the amount of mass in one liter of water at 4 degrees C.
Term
 Law of inertia
Definition
 Also known as Newton's First Law Every body continues in its state of rest, or motion in a straight line as a constant speed, unless it is compelled to change that stat by a net force exerted upon it
Term
 Mass
Definition
 A measure of an object's iertia; also a measure on the amount of matter in an object. Depends only on the amount of and kind of particles that compose an object - not on its location.
Term
 net force
Definition
 The combination of all the force that act on an object.
Term
 newton
Definition
 SI unit of force. One newton (N) is the force applied to a one-kilogram mass that will produce an accelleration of one meter per second per second.
Term
 normal force
Definition
 For an object resting on a horizontal surface, the upward force that balances the weight of athe object; also called the support force.
Term
 support force
Definition
 Same as the normal force
Term
 weight
Definition
 The force on a body due to the gravitational attraction of another body. [EARTH's]
Term
 What distinction did Aristotle make between natural motion and violent motion?
Definition
 Natural motion is straight up or down and circularViolent motion was imposed motion caused by an external force.
Term
 What does friction cause? Or, what is the cause of friction?
Definition
 Friction is caused by the irregularities in the surface it is touching.Friction causes objects in motion to slow down and eventually stop.
Term
 Given: A ball rolling down an inclined plane.How far up an inclined plane will the ball roll back up?
Definition
 NEARLY, the same height as the initial starting point.
