Friction and Gravity Crossword Puzzle

QUESTIONS LIST:

• friction : surface resistance to relative motion, as of a body sliding or rolling.
• gravity : the force of attraction by which terrestrial bodies tend to fall toward the center of the earth.
• unbalanced force : forces that cause a change in the motion of an object
• balanced force : balance forces are two forces acting in opposite directions on an object, and equal in size
• second : _ law of motion - the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object
• surface : the outside part or uppermost layer of something
• third : _ law of motion - for every action, there is an equal and opposite reaction.
• newton : an english mathematician, astronomer, theologian, author and physicist who is widely recognized as one of the most influential scientists of all time. 3 laws of motion
• inertia : the property of matter by which it retains its state of rest or its velocity along a straight line so long as it is not acted upon by an external force.
• mass : mass is both a property of a physical body and a measure of its resistance to acceleration (a change in its state of motion) when a net force is applied
