What are the units for mass? Come up with as many as you can
Kilograms, grams, pounds, ounces
100
True or False: The lighter the mass of an object, the more inertia it has.
False
100
Mr. Stockert runs 50 yards in 10 seconds and Mrs. Moore can run 100 yards in 20 seconds. Who has the faster speed? Show your knowledge with the speed equation.
Speed = distance/ time Stockert = 50 yds/ 10 s = 5 yds/s Moore = 100 yds/ 20 s = 5 yds/s They are the same speed!
100
Which Newton's Law is being described here? I don't sink into the ground because the ground is pushing up on me as hard as I am pushing down on it
Newton's 3rd Law
200
a Force that is either attractive or repulsive
Magnetic or Electric Force
200
What are the units for speed? Come up with as many as you can
meters/second inches/millisecond miles/ hour
200
Petyon Manning yells, "Omaha", and then throws a lateral pass. What is the pathway of the ball called?
trajectory
200
Brandon McManus kicked a 52 yard field goal in 4 seconds again the New England Patriots. What was the speed of the kicker?
Speed = distance/ time Speed = 52 yards/ 4 seconds = 13 yds/s
200
A spacecraft propels itself through space and then maintains its motion even without rocket boosters when in deep space. Which law tells us why the rocket continues to move into space?
Newton's 1st Law
300
A force that holds back the movement of a sliding object
Friction
300
What are the units for velocity?
mph North, m/s East, Any speed with a direction

Vernon Walker and Tra Gallegos are watching the Superbowl game in different parts of the stadium. Suddenly a player catches a Hail Mary! Vernon says," The ball was thrown to the right!" Tra says, "No way, the ball went straight up." Why do they have different answers to the same trajectory of the ball ?
They have a different frames of reference
300
Mrs. Gunn like to ski Powderhorn black diamonds. Her first run of the day is 1 mile Northeast for 15 minutes! What is her velocity?
Velocity = Speed + direction Speed = distance/ time Speed = 1 mile/ 15 minutes = .066miles/min Northeast direction
300
Which Newton's law describes this? Even though its very heavy, the massive force of the space shuttle's booster rockets accelerate it to amazing speeds on its way to Earth.
Newton's 2nd Law
400
How fast an object is moving in a particular direction
Velocity
400
What are the units for force?
Newtons
400
In the picture, are the forces balanced or unbalanced. How do you know? Draw an arrow in the direction of the force.
First balanced Second unbalanced
400
A Ferrari starts from rest and after 3.6 seconds travels at a rate of 1,000 m/s. What is the car's acceleration? Use the acceleration equation.
Acceleration= Final velocity - initial velocity/ time A = 1,000 m/s - 0 m/s(rest) / 2 seconds A = 500 m/s^2
400
What Newton's law is describe? If I play pool on a pool table with no friction at all, after my first shot the balls will bounce until they go in a pocket. A game of pool will only last one shot.
Newton's 1st Law
500
the tendency for an object to resist a change in motion
Inertia
500
What are the units for acceleration?
m/s^2

How does the violin relate to Newton's laws? Describe all of three of Newton's laws in this!
NL 1: When strings are plucked, they remain in motion, unless acted by an unbalanced force. NL2: When a person uses a greater force on the bow to push down on the strings, they make a larger sound ( acceleration) NL 3: Pushing bow on strings, the strings push back or sounds waves hit the wall, and they bounce back
500
A runner covers the last stretch of a race in 4 seconds. During that time, she speeds up from 5 m/s to 9m/s. What is the runner's acceleration in this part of the race?
Acceleration = Final velocity - initial velocity / Time A = 9 m/s - 5 m/s / 4 seconds A = 4 m/s / 4 seconds = 1 m/s ^2
500
2 wrastlers go mano y mano. One weighs 90 kg and the other weighs 40 kg, which one has more force? What Newton's law is being applied.
The forces are equal and opposite due to Newton's 3rd Law. The accelerations are different! F = ma F = F Ma = mA
