Sir Isaac Newtons lived during the 1600s. Like all scientists, he made observations about the world around him. Some of his observations were about motion. His observations have been supported by more data over time; and we now call these Newton’s Laws of Motion. His laws of motion explain rest, constant motion, accelerated motion, and describe how balanced and unbalanced forces act to cause these states of motion.

Review the three laws of motion:

• Newton’s first law of motion says that an object at rest will stay at rest and an object in motion will stay in motion until acted upon by an outside, unbalanced, external force.

• An object will not change its motion unless a force acts on it.

• An object that is not moving remains at rest until something pushes or pull it.

• An object that is moving remain moving, at the same velocity, until something pushes or pulls it to change its speed or direction.

• All objects resist having their motion changed.

• This tendency to resist a change in motion is called inertia.

• The more mass an object has, the greater its inertia.

• The second law of motion states that the force of an object is equal to its mass times its acceleration.

• A change in motion occurs only if a net force is exerted on an object.

• A net force changes the velocity of the object, and causes it to accelerate.

• If an object is acted upon by a net force, the change in velocity will be in the direction of the net force.

• The acceleration of an object depends on its mass.

• The more mass an object has or the more inertia it has, the harder it is to accelerate.

• More mass means less acceleration if the force acting on the object is the same.

• Newton’s third law of motion states that for every action there is an equal and opposite reaction.

• When one object exerts a force on a second object, the second object exerts an equal force in the opposite directions on the first object.

• The force exerted by the first object is the action force.

• The force exerted by the second object is the reaction force.

What to do:

1. Create a slideshow presentation: Title Slide + 3 slides (one for each law)

2. Choose a sport from the teacher approved list

3. Include an explanation of how the sport demonstrates or describes the law of motion. Include an image (properly attributed) that illustrates the explanation.

How you will be evaluated:

This counts as a TEST grade!

Your slideshow will be checked for these things:

• Accuracy & completion (62.5% of grade). An incomplete slideshow or explanation will not be completely accurate.

• Visual Appeal (25% of grade). This includes color and type of font and organization of slides. Proper spelling and grammar are also key to having great visual appeal.

• Appropriate Attributions of photos (12.5% of grade). Images must be properly attributed or cited using commons.wikimedia.org or search.creativecommons.org

• Bonus Points will be issued for sharing presentation with the class on the due date.

Rubric will be used 3 times/once per law of motion
