What is newton's first law? please give an example
An object in motion will stay in motion and an object at rest will stay at rest; unless acted upon by an unbalanced force.
Table cloth pull
Cars and Ramps
Tug of War Rope
Others - TBD
What is a contact force
A force that requires matter/touching matter in order to work
What is a reference point
the starting point
a point that can be used to determine if an object ahs moved or not
What is the DV?
Mrs. Coghill has three basil plants and wants to see if different types of fertilizer will affect the growth of the plant
DV = plant growth
Who created the three laws of motion?
What is Newton's Second Law? Give an example
An objects acceleration (changing of speed or direction) depends on the mass of the object and the net force applied to the object
Force = Mass x Acceleration
Skateboards Mass
pushing alight object vs. a heavy object (which requires more force)
Others TBD
Name three contact forces
friction
air resistance
Applied Force
Buoyancy
Mrs. Coghill ran 20m in 10 seconds. Calculate the speed. Don't forget your units
2m/s
What is the IV?
Mrs. Coghill has three basil plants and wants to see if different types of fertilizer will affect the growth of the plant
IV - types of fertilizer
If you rub your hands together, what type of force is created?
Friction
What is Newton's Third Law? Give an example
For every action there is an equal and opposite reaction
ball bouncing off a wall
paper airplane
releasing a balloon filled with air
Others TBD
Name Three Non Contact Forces
Gravity
Magnetism
Electrical Force
Describe the motion of this object
The object ran/walked 5 meters in 5 seconds
Stopped for 5 seconds
Ran/walked back to the reference point in 5 seconds
Create a hypothesis from the following:
I want to see if filling my hot air balloon for 30 sec, 45 sec, and 60 sec will affect how long it stays in the air
If I fill the balloon for ______ sec, then the balloon will stay in the air the longest.
Calculate the distance (must include units):
My dog chased a tennis ball at a speed of 5m/s for 10 seconds
50m
Which one of newton's laws does this describe?
Mrs. Coghill gets super upset when she discovers her leftover pizza was eaten by Mr. Coghill. Out of anger, she punches the wall and hurts her hand.
Newton's Third Law (equal and opposite)
What is the opposite force of gravity?
Normal force
Draw a distance time graph that represents the following (dont forget to include ALL parts of the graph!):
A car travelled 3m in 3 seconds
The car stopped at a light for 5 seconds
The car travelled 2m in 2 seconds
See board
Create a data table from the following information:
I want to see if filling my hot air balloon for 30 sec, 45 sec, and 60 sec will affect how long it stays in the air
30 second fill - flight time: 10 sec, 15 second, 12 second
45 second fill - flight time: 20 sec, 22 sec, 25 sec
60 second fill - flight time: 30 sec, 35 sec, 40 sec
Your table must have all required parts
labels
three trials
averages

Newton's first law is also known as the law of ...
You're pulling a skateboard using 30N of force with 20kg of mass on the board. If you increase the mass to 40kg, what will happen to the acceleration?
The acceleration will decrease
It takes more force in order to maintain the acceleration
Calculate the net force and tell me if its balanced or unbalanced. DONT FORGET YOUR UNITS
10N to the right unbalanced
Calculate the speed at 5 seconds
1 m/s
Create a graph (using all parts and labels) of the following data
I want to see if filling my hot air balloon for 30 sec, 45 sec, and 60 sec will affect how long it stays in the air
Averages:
30 sec fill: 12 sec
45 sec fill: 21 sec
60 sec fill: 30 sec

According to Newton's 2nd law, an object with a lot of mass requires...
a lot of force to move
