If one person is pushing on a box with 3 Newtons of force to the left, and another person is pushing on the same box with 11 Newtons of force to the right, what is the net force? *Give number and direction
What is 8 Newtons to the right?
200
This is resistance of an object to change its speed or the direction of its motion.
What is inertia?
200
The change of position in an object.
What is motion?
200
An object in motion will __________________ unless _______________________.
What is "remain in motion" unless "acted upon by an unbalanced force".

Two teams are playing kickball. Tommy kicks the ball where it rolls far into the outfield. Before anyone can get it, the ball stops. What made it stop?
What is friction?
200
In a tug of war, the red team is pulling on a rope with 38 Newtons of force to the left, and the blue team is pulling with 42 Newtons of force to the right. What is the net force, and who wins?
The net force is 4, and the Blue team wins.
300
Newton's second law of motion states that the change in an object's motion depends on its _______ and the force acting upon it.
What is mass?
300
If a car goes from 30 mph to 50 mph, the cars motion is ___________.
What is accelerating?
300
A baseball player hits a pop-up ball. The ball soars high into the air but eventually falls. This force made it fall.
What is gravity?
300
The surface with less friction, carpet or ice.
What is ice?
300

What is 80 mph?
400
Newton's Law exhibited here...
Andy pushes his skates backward in order for his body to lunge forward.
What is Newton's Third Law of Motion?
400
What is taking place during section B?
What is constant speed?
400
When an unbalanced force acts upon an object, the object will move in this direction.
What is the direction the force is going?
400
Newton's third law of motion states that for every _________ there is an ________ and _______ __________
What is for every "action" there is an "equal" and "opposite" reaction?
400
A child weighing 20 kg is accelerating at 2 m/s when she runs into a tree. With what amount of force did the child hit the tree.
40 N
500
The formula for Newton's Second Law of Motion.
What is f=m x a?
500
Rubbing of one object against another object. (A force that opposes (goes against) motion.)
What is friction?
500
These forces can cancel each other out. Any time there is this kind of force, the object does not move.
What is balanced force?
500
An object with a greater mass requires this to move at the same rate.
What is a greater force to move it?
500
A car is travels a distance of 500 miles and it takes 10 hours. At what speed was the car travelling?
What is 50 mph?
