Drag and drop the vocabulary word with it's matching definition. This is a force which resists all motion, this is an attractive force between any two objects due to mass, for every action there is an equal and opposite reaction, this is the SI (metric) unit of force, a law of motion that states that and object stays at rest and one in motion stays in motion, this says the acceleration of an object increases by the force applied to it and decreases based on its mass, in the second law of motion it is mass x acceleration the ability to apply a chance in velocity on a given object, this is what causes acceleration two forces acting opposite eachother. The options are newtons second law, newtons first law, force, newtons third law, gravity, unbalanced forces, friction, and newton.
Force: a push or pull on an object.
Gravity: an attractive force between any two objects due to their mass.
Newton: the SI (metric) unit of force.
Newton's First Law: a law of motion that states that an object at rest tends to stay at rest, and an object in motion tends to stay in motion with the same velocity, unless acted upon by an external force.
Newton's Second Law: a law of motion that states that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass (F = ma).
Newton's Third Law: a law of motion that states that for every action, there is an equal and opposite reaction.
Friction: a force that resists the motion of an object.
Unbalanced Forces: forces that are not equal and opposite, resulting in a change in motion.
