| Newton's First Law | Newton's Second Law | Newton's Third Law | Net Force |
|---|---|---|---|
|
An object in motion stays in motion or an object at rest stays at rest, unless acted on by an UNBALANCED force.
State Newton's First Law of Motion.
|
An object's acceleration are affected by two things: mass and force.
State Newton's Second Law of Motion.
|
To every action there is an EQUAL and OPPOSITE reaction.
State Newton's Third Law of Motion.
|
No change in motion
What is the outcome of balanced forces?
|
|
Law of Inertia
State the shorthand version of Newton's First Law of Motion.
|
Force = Mass (x) Acceleration
State the shorthand version of Newton's Second Law of Motion.
|
ACTION = REACTION
State the shorthand version of Newton's Third Law of Motion.
|
Change in motion (or) acceleration
What is the outcome of unbalanced forces?
|
|
Apply an unbalanced force to it.
How do you make an object CHANGE its motion?
|
The car is easier to push because it has LESS MASS.
Explain why the following scenario applies to Newton's Second Law of Motion: A car is easier to push than a bus.
|
Action = Foot hits ball
Reaction = Ball hits foot back with equal and opposite force
Identify the action and reaction to the following scenario: A man kicking a soccer ball.
|
Subtract the forces
How do you calculate net force of force pair arrows that are moving in opposite directions?
|
|
You are in motion with the fourwheeler, when the four wheeler hits the fence there is no force that stops you so you continue to move.
Explain how the following scenario applies to Newton's First Law of Motion: You are thrown off the front of a 4 wheeler when it runs into a fence.
|
The baseball went farther because it has less mass.
Explain why the following scenario applies to Newton's Second Law of Motion: The baseball went farther than the basketball when your classmate hit them with a bat.
|
.......
State and explain a real world example of Newton's Third Law of Motion.
|
0 Newtons
What is the net force of a box being pushed with 20 N of force to the right and 20 N of force to the left?
|
|
The fence is the unbalanced force that stops the kickball.
Explain how the following scenario applies to Newton's First Law of Motion: A kickball continues to roll until it hits the fence.
|
Apply more force to the cart.
You are pushing a grocery cart. At every stop, your friend adds more groceries to the cart. What needs to happen for you to be able to accelerate the cart with more groceries in it?
|
Neither has more force on the other. Newton's third law states that to every action there is an EQUAL / OPPOSITE reaction. Therefore, the two forces would be the SAME.
TRICK QUESTION: According to Newton's Third Law of Motion, if you are punching a punching bag, which object has more force on the other? The fist punching the bag or the bag punching the fist?
|
20 Newtons of force to the right
What is the net force of a box being pushed with 40 N of force to the right and 20 N of force to the left?
