## New·ton's first law

(no͞ot′nz, nyo͞ot′-)
n.
The principle stating that a body at rest will remain at rest, and a body in motion will remain in motion with a constant velocity, unless acted upon by a force. Also called law of inertia.

[After Isaac Newton.]

According to Newton's first law, "an object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Newton's first law states that for every action there is an equal and positive a reaction, so weather you are up a ladder trimming the tops of trees (reaction: vertigo and a bitter regret that you did not get a professional in to do it) to spray painting the fence panels (reaction: pressurised container springs a leak and the electric compressor keeps on running, yours truly gets covered in high pressure orange fence panel paint).
When your plane is stationary, it's a good time to consider Isaac Newton's First Law of Motion, regarding inertia.
Newton's first law highlights the effort it requires to overcome inertia.
Newton's First Law of Motion: Every object in a state of uniform motion (or at rest) tends to remain in that state of motion (or at rest) unless an external force is applied to it.
The group has met weekly, covering a variety of STEM-focused topics such as the Scientific Method, Bernoulli's Principle, Pascal's Law, Newton's first law of motion and more.
Newton's first law states that inertia or mass is the property of matter that resists changes in motion, whereas drag is the resistance to motion.
The three topics chosen were Newton's First Law, Straight Line (Accelerated) Motion and Momentum.
As they explore buoyancy, they'll learn about the forces of gravity and lift, the densities of air and helium, and Newton's First Law.
NEWTON'S FIRST LAW OF MOTION, also known as the principle of inertia, says "Every body perseveres in its state of being at rest or of moving uniformly straight forward, except insofar as it is compelled to change its state by forces impressed.
Recalling Newton's first law that mass needs an outside force to compel its motion, one realizes that there would be no accidents to investigate without "a" because "m" would remain at rest.
