Newton's First Law of Motion An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Mass The amount of matter in an object
Balanced Forces Forces that are equal and opposite and produce no change in the motion on an object. Unbalanced Forces – Forces that produce change in the motion of the object in the direction of the greatest force.
Unbalanced Forces Forces that produce change in the motion of the object in the direction of the greatest force.
Acceleration A change in velocity, or the objects position and speed.
Velocity The speed and direction of an object.
Speed The distance an object moves in a specific time.
Net Force the total of all the forces acting on an object
