1st Law
Definition - What does Newton’s 1st law state?
Objects at rest remain at rest and objects in motion stay in motion unless acted upon by unbalanced forces
Force - What unit is force measured in?
Newtons
Action and Reaction - Are action and reaction opposites and why?
Yes because when one force occurs there is always another force pushing back on that one.
Net Force - If there is a balanced force then what is the net force always?
The net force is always 0.
Definition - What does Newton's 2nd law state?
Force = Mass x acceleration
Definition - What does Newton's 3rd Law state?
For every action, there is an equal and opposite reaction.
Balanced Forces - Balanced forces are ____ in size, _____ in direction, __ __ change the motion.
Equal, Opposite, Do Not
Mass - What is mass always measured in?
Kilo grams
Definition - For every ____ there is a ____ and ______ reaction
Action, Equal, Opposite
Which of these would correctly describe Newton’s 1st law and act that one out.
A rocket launching
A car staying parked until you start the engine.
2. A car staying parked until you start the engine.
Example of the law in the real world
If a book is sitting on a table what forces are acting on it?
F grav and F norm.
What is acceleration always measured in?
Example of Law in the Real World - How is swimming a real life example of this law?
When you swim you push water backward and the water pushes you forward.
Which of the following correctly describes Newton’s second law and act it out.
Stopping a grocery cart to get some food.
1. Pushing a really heavy cart of groceries vs pushing a light cart.
Example of law in real world - How is pedaling a bicycle harder which makes the bike go faster an example of Newton’s second law.
You are putting more force into pedaling the bike which in turn makes the bike accelerate faster which is as Newton’s second law states because the mass stays the same but the force and acceleration increases.
Which of these correctly describes Newton’s third Law and act it out.
A book staying on a shelf
Playing Tug of War where one team has more people.
Jumping up and down.
3. Jumping up and down
