Define the Law
What is Newton's First Law of Motion?
This law states an object at rest stays at rest unless acted upon by an unbalanced force.
What is Inertia?
The tendency of an object to resist changes in its state of motion.
What is a Newton?
The unit of measurement for Force.
What is the floor pushing up on you?
When you push down on the floor to jump, this is the reaction force.
What is Newton's First Law?
A book sitting still on a table is primarily an example of this law in action (until moved).
What is Newton's Second Law of Motion?
The mathematical formula F = ma is associated with this law
What is Inertia / Newton's First Law?
Why you lurch forward in a car when the driver suddenly slams on the brakes.
What is the ping pong ball?
If you apply the same force to a ping pong ball and a bowling ball, this ball will have much greater acceleration.
What is the cannonball pushing back on the cannon (recoil)?
The force pair involved when a cannon fires a cannonball (Action: cannon pushes ball).
What is Newton's Second Law?
A baseball player hits a ball harder to make it go farther, applying principles of this law.
What is Newton's Third Law of Motion?
This law explains that forces always occur in pairs.
What is Inertia / Newton's First Law?
Pulling a tablecloth quickly from under dishes relies on this property of the dishes.
What is double the acceleration?
Doubling the net force on an object while keeping mass constant does this to the acceleration
What is a rocket? (Reaction: Air/gas pushing rocket up)
Hot gas pushing down is the action force for this flying object.
What is Newton's Third Law?
Stepping off a small boat onto a dock often causes the boat to move backward, demonstrating this law.
What is Newton's Second Law of Motion?
This law connects net force, mass, and acceleration.
What is Newton's First Law?
A soccer ball won't move until a player kicks it, demonstrating this law.
What is Force?
It's harder to push a heavy box than a light box up the same ramp because the heavy box requires more of this.
What is the water?
When you swim, you push water backward (action). This pushes you forward (reaction).
What is Newton's First Law (Inertia)?
Wearing a seatbelt helps protect you because of your body's tendency to keep moving, related to this law.
What is Newton's Third Law of Motion?
"For every action, there is an equal and opposite reaction" is the summary of this law.
What is Inertia / Newton's First Law?
Shaking a wet towel snaps the water off because the water continues moving when the towel stops, due to this.
What is 4m/s2? (a=F/m=20N/5kg)
The acceleration of a 5 kg object when a 20 N net force is applied. (F=ma)
What is an equal force?
if you lean against a wall, the wall pushes back on you with this magnitude of force compared to your push.
What is Newton's Second Law?
Why a lighter car generally gets better gas mileage than a heavier car (less force needed for same acceleration).
