Newton's First Law
What does Newton's First Law state?
Objects in motion stay in motion and objects at rest stay at rest
What does Newton's Second Law state?
The acceleration of an object depends on the mass and how much force is applied.
What does Newton's Third Law state?
For every action there is an equal and opposite reaction
What is a force field?
a force (magnetic, electric, or gravitational) felt over an area of space. It acts at a distance WITHOUT touching.
What concept is a big part of Newton's First Law?
Inertia
What is the equation for Newton's Second Law?
F=MA
Which of the following is NOT an example of Newton's Third Law?
a. Firefighters hold hoses firmly because the water shoots out, the hose is pushed back.
b. A cannon jumps back as a soldier fires it.
c. A car speeding on the highway slows down when they see a police car.
d. When you sit in your chair, your body exerts a downward force on the chair and the chair exerts an upward force on your body.
c. A car speeding on the highway slows down when they see a police car.
What is a magnetic field?
The area around a magnet where magnetism can be felt.
If you're riding a horse and your horse suddenly stops just before a jump, you will most likely continue moving forward due to...
Inertia
What scientific concepts are shown in Newtons Second Law?
Force, Mass, and Acceleration

Action: the hammer
reaction: the nail
What is an electromagnetic force?
When an electric current passes through a wire, a magnetic field is formed.
You are riding roller skates downhill. You are not able to stop until you grab on to a stop sign. What scientific concept is being described?
A body in motion will stay in motion unless influenced by an outside force.

What is an electric field?
The area around any electrically- charged object where the object's force is exerted on other charged objects.
What forces are in play during a game of tug of war?
Balance and Unbalanced forces
