Newtons Laws of Motion Foldable 1Cut and paste

Newton’s Laws of Motion Foldable 1)Cut and paste your foldable like the one shown on the right. 2) Cut along the SOLID lines only – and you will make flaps. 3) On the inside, write down what the law states. (Add a formula if there is one. ) 4) Write down an example of a situation that shows the law in action.

st Newton’s 1 Law

Newton’s 1 st Law of Motion • After the ball is kicked, what forces are acting on it while it rolls? • What if we could remove those forces? What would happen then if we kicked the ball? GRAVITY Friction

Newton’s st 1 Law of Motion • Newton’s 1 st law of motion states: An object at rest will remain at rest, -andan object moving at a constant velocity will continue moving at a constant velocity, -UNLESSit is acted upon by an unbalanced force.

Newton’s st 1 Law of Motion BASICALLY… Objects resist any change to their motion! That’s because larger objects have more inertia (more resistance a change in This resistance is calledto INERTIA. their motion)! Which one would be easier to push? or…

Let’s cover Newton’s 1 st Law • This law deals with situations where forces are balanced… • When forces are balanced, objects resist any changes in their motion… that’s called INERTIA.

Newton’s 1 st Law of Motion • If no one kicks the ball, what will happen? • Objects at rest will remain at rest…

Newton’s 1 st Law of Motion • If there was NO FRICTION (no unbalanced force) to slow down the ball, what would happen? • Objects in motion will remain in motion …

nd Newton’s 2 Law

Newton’s 2 nd Law of Motion • Newton’s 2 nd law of motion describes how UNBALANCED FORCES and MASS affect the ACCELERATION of an object.

So, how do unbalanced forces affect an object’s motion? • How does a batter’s swing affect the acceleration of a baseball? Sacrifice Bunt Homerun Hit

So, how do unbalanced forces affect an object’s motion? • The harder you hit, the faster it goes! • The greater the force, the greater the acceleration… Sacrifice Bunt Homerun Hit

So, how does mass affect an object’s motion? • Which shopping cart would move faster with a single push? Empty Cart Full Cart

So, how does mass affect an object’s motion? • The fuller the cart, the slower it goes! • The more mass, the less acceleration… Empty Cart Full Cart

Newton’s 2 nd Law of Motion It states: ACCELERATION depends on the object’s MASS, and the net FORCE acting on the object. • We can also write it mathematically: Force = Mass x Acceleration

rd Newton’s 3 Law

Which forces are acting to get this guy up in the air? His feet push DOWN on the ground. • But wait… His downward push can’t be causing his upward motion.

Which forces are acting to get this guy up in the air? His feet push DOWN on the ground. The ground pushes UP on the man. • There must be a force pushing UP! • The force of the ground pushes him UP!

Newton’s rd 3 Law of Motion ALL forces act in PAIRS! Action Force: Man’s feet push DOWN on the ground. Reaction Force: Ground pushes UP on the man. • Newton’s 3 rd law says that: For every action force, there is an equal and opposite reaction force.
