Motion, Forces and Energy Crossword Puzzle

QUESTIONS LIST: speed: distance an object travels in a given unit of time, net force: combination of all forces acting on the object, momentum: product of an object's mass and velocity, weight: force of gravity on a person/object, force: push or pull on an object, projectile: an object that is thrown, motion: when one object's distance from another is changing, inertia: tendency of an object to resist a change in motion, second: newton's _ law - acceleration depends on an object's mass and the net force acting on the object, velocity: speed in a given direction, friction: force that 2 surfaces exert on each other when they rub against each other, reference point: object that is used to determine if something is in motion, acceleration: rate at which velocity changes, mass: amount of matter in an object, third: newton's _ law - for every action there is an equal but opposite reaction, first: newton's _ law - an object at rest will stat at rest and an object in motion with stay in motion, gravity: force that pulls objects toward each other, newton: si unit that measures strength of force, balanced: _ force - equal forces acting on an object in opposite directions, air resistance: fluid friction on objects falling through the air, unbalanced: _ force cause an object to start moving, stop moving, or change direction
