Forces and Energy Goal 1 (U1G1)
Terms in this set (17)
a push/pull exerted on an object.
the place or the object that is used to determine if another object is in motion.
arrow that shows magnitude of force and direction.
magnitude of force
how much force is being applied to an object (NOT the total).
the total amount of force acting on an object.
the tendency for an object to maintain momentum.
a force that resists the relative motion of two bodies in contact.
the resistance caused by a gas to the motion of a solid body moving through it.
the force of friction is greater than the applied force. (object is not moving)
the force that slows down the motion of a rolling object.
kinetic (sliding) friction
if you apply more force than friction, the object will "break free" and slide.
a force that slows down the motion of an object through a fluid or through the air.
equal forces acting on an object in opposite directions. These forces keep an object NOT moving.
forces that produce a nonzero net force, which changes an object's motion. (object is moving)
Newton's First Law of Motion
an object at rest stays and rest, and an object in motion stays in motion unless acted upon by an unbalanced force. (inertia)
Newton's Second Law of Motion
the acceleration of an object depends on the mass of the object and the force applied to it. (F=ma)
Newton's Third Law of Motion
every action has an equal and opposite reaction.
