You are reviewing your results from an experiment involving a soccer ball being kicked. You claimed that, "unbalanced forces were exerted on the soccer ball, causing the ball to move and also eventually stop." Please support the best
justification that supports your claim.
Š
When I kicked the ball, the ball moved in the direction that my
leg was kicking it. This is because when my foot hit the ball my
force overcame the gravity holding the ball down. Gravity
eventually pushed the ball back down but only after I scored a
goall!
My foot applied an unbalanced force to the ball. I knew this
happened because the ball sitting still meant the forces were
balanced and only unbalanced forces can cause a ball to move.
The ball went 30ft in 5 seconds, so it's speed was 6m/s.
When I kicked the ball, I was applying an unbalanced force.
This force accelerated the ball away from me and because the
ball accelerated I know my force was unbalanced. As the ball
traveled through the air, air resistance caused the ball to slow
down, gravity pulled it back down, and rolling friction on the
ground caused it to stop
Newton's first law said that the ball would sit still until
something acted on it, so I acted on it. Newton's second law
made the ball move forward because it has a small mass. And
Newton's third law explains why the ball hit me back when I
kicked it. Sliding friction eventually made the ball stop,
