If a box is initially pushed left with a force of 5 Newtons, but is also pushed right with a force of 5 Newtons at the same time, the box will move in this direction.
What is remain motionless?

While trying to calculate his average speed, Mark realized he arrived at school in just 30 minutes (1800 seconds), although he had to ride his bike nearly 900 meters.
What is 0.5 meters per second?
100
This Law of Newton (1st, 2nd, or 3rd) is also known as the Law of Inertia.
What is Newton's 1st Law of Motion?
100
The force exerted when two surfaces rub against one another.
What is friction?
100
(View the graph on the board) An example of this is what is happening from time 0-3 seconds on the graph.
What is constant speed (or constant velocity)?
200
If a large safe is initially pushed right with a force of 20 Newtons, while another force pushes left at the same time with a force of 25 Newtons, the safe will move in this direction with this amount of force.
What is left with a force of 5 Newtons?

Mr. Grivna wanted to know his speed. His data book showed that in the time span of 20 seconds, he had increased his distance from 0 meters to 40 meters.
What is 2 meters per second?
200
This Law of Newton (1st, 2nd, or 3rd) can be illustrated by the difference in how long it takes for a large truck versus a small car to slow down.
What is Newton's 2nd Law of Motion? (F=m*a)
200
This force pulls objects towards the earth's surface at an acceleration of 9.8 meters per second squared?
What is gravity?
200
(View the graph on the board) An example of this is what is happening from time 3-6 seconds on the graph.
What is no motion?

A motionless car that sits on a friction-less surface is pushed north at a force of 7 Newtons, while an opposing force pushes south at 6 Newtons. The car will move in this direction with this amount of force.
What is north at 1 Newton?
300
A car's speed is this if it travels 50 kilometers in 5 hours.
What is 10 kilometers per hour?
300
This is the reason why you are thrown forwards when a car slams on its brakes.
What is Newton's 1st Law of Motion?
300
This causes objects that are falling due to gravity to reach their terminal velocity, meaning that they will continue to fall at a constant speed, instead of accelerating any further.
What is air resistance?
300
(View the graph on the board) An example of this is what is happening from time 6-9 seconds on the graph.
What is acceleration?
400
When astronauts on the moon realized that gravity was less than that on Earth, they immediately knew that this quantity was most different as well (their mass, their volume, their weight, or their height).
What is their weight?
400
Ms. Mullican's speed is this if she traveled from the 25-yard line to the 35-yard line in a time of 0.5 seconds.
What is 20 yards per second?
400
When you push an object with a force of x, that objects also pushes back on you with a force of x.
What is Newton's 3rd Law of Motion?
400
This force always directly opposes the direction of motion.
What is friction?
400
(View the graph on the board) An example of this is what is happening from time 9-12 seconds on the graph.
What is deceleration?
500
An example would be that this type of force is acting on a car if it is traveling at a constant rate of speed.
What is a balanced force?
500
Mr. Jarman decides that he is going to hit a homerun today. The ball's speed is this if the ball travels 400 yards in 8 seconds.
What is 50 yards per second?
500
This is a unit of force.
What is a newton?
500
This is the combination of all forces acting on any particular object at any given time.
What is a net force?

(View the graph on the board) An example of this is what is happening from time 12-15 seconds on the graph.
