Definitions
100
An object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
What is Newton's First Law of Motion
100
Label “distance” and “time” on the x and y axis of this graph
distance: y axis
Time: x-axis

While you are playing soccer, you kick a ball that is at rest in the center of the field and then it travels to your teammate. This is an example of which law of motion?
What is Newton's 1st law.
100
Which force caused the car on the bumpy ramp lose the race when racing against the car on smooth ramp?
Friction!
100
The amount of matter in an object
What is Mass?
200
This is the natural tendency of objects to keep on doing what they're doing.
What is Inertia
200
What is the relationship between time and distance in this graph?
Both are Increasing (directly correlated)
200
A seatbelt holds you back so you don't fly out of the car. This is an example of which law of motion?
What is Newton's First Law.
200
What two things did we need to measure in order to find speed of cars in Tuesday's lab?
Distance traveled and time of travel
200
What is the distance traveled per unit of time?
What is Speed.
300
F = M * A
Force = Mass x Acceleration
What is Newton's Second Law of Motion
300
What is the relationship between time (x) and speed (y) in this graph?
As time increases, speed decreases (acceleration is decreasing). AKA time and speed are Inversely correlated.
300
You left your book on a desk in Mrs. Buckalew's room and it is still there the next morning. This is an example of which law of motion?
What is Newton's First Law.
300
Which car had a greater speed from Tuesday's lab? Car with pennies (high mass)? or car with no pennies (low mass)?
Trick question! Neither! Both cars went at the same speed because gravitational acceleration (change in speed) is the same for all objects, no matter the mass.
300
What is the change in speed over time?
What is Acceleration
400
The rate of change in speed (Hint: speed lab)
What is acceleration?

Find the rate of Scottie's tennis ball in this graph from 0-5 seconds.
2 feet/second
400
You push over a kickball from the roof of your apartment, the force with which it falls is equal to its mass of 1kg and its gravitational acceleration of 9.8m/s^2
What is Newton's Second Law.
400
Kaleel and Marcus are discussing whether a piece of paper or a golf ball will reach the floor first in a vacuum (no forces except for the force of gravity acting on objects). Marcus says it is obvious that the heavier object will reach the floor first. Is Marcus correct? Why or Why Not?
Marcus is INCORRECT!! Gravitational acceleration is EQUAL for all objects (no matter the mass) so therefore the paper and the golf ball will accelerate at the same rate and reach the ground at the SAME TIME in a vacuum.
400
This is a push or pull that needs to be provided to put an object into motion or into rest
What is a force?
500
This law describes that if Force is Constant, and Mass increases, acceleration will decrease.
Newton's second law

Find the rate of Kayla’s bike during minutes 8-14.
0 yards/minute. The bike is not budging!!

In order to hold your head up, your neck is constantly using muscles. The heavier your head, the stronger the muscles you need in your neck. Which law am I?
What is Newton's Second Law.

In the game tug of war, Adrian is pulling with a force of 30N. His opponent, John, is pulling with a force of 30N. Who will win the game?
Neither! They forces cancel out and there will be no winner.

“If an object is at rest, this means that the forces in each direction are ______”
EQUAL
