Newton's First Law of Motion An object that is at rest will stay at rest until an unbalanced force acts upon it An object that is in motion
will not change its velocity
until an unbalanced force acts upon it.
A golf ball in Motion is stopped by the
wind is that unbalanced force USING GOLF TO EXPLAIN
NEWTON'S LAWS OF MOTION Newton's Second law of Motion Newton's second law states that the force applied to a body produces a proportional acceleration; the relationship between the two is F=ma. Force equals mass times acceleration. The more mass the more force needed to accelerate it A bowling ball has more mass
than a golf ball .045 kg golf ball 7.26 kg bowling ball To reach 4 meters/second F=ma F=7.26x4 =11.26 newtons of force needed F=.045x4 =.18 newtons of force needed There is more force needed to
get the bowling ball moving at 4
meters/second/second than
the golf ball to move at 4
meters/second/second The object acted on by a force will
accelerate in the direction of the force. Newton's third law of motion For every action there is an
equal and opposite reaction This means that when the golf club hits the
golf ball the golf ball hits the club back with
the same amount of force. The End
