Newton Three Laws of

Newton's 1st, 2nd and 3rd law of Motion

The First Law of motion is also called what? The Law of Inertia
Inertia depends on what? Mass
What are two forces on Earth that are almost always present? Gravity and Friction
What is Inertia? A resistance to a change in motion
What kind of forces cause an object to move? Unbalanced Forces
Why can't an object be in free fall in the open air on earth? Air Resistance
What is an airless area? A vacuum
What is the greatest velocity a falling object reaches? Terminal Velocity
What causes you to move forward when your car suddenly stops? inertia
What is friction? When two moving objects rub against each other
Who developed the FIRST LAW OF MOTION? Isacc Newton
Sliding friction occurs when two solid surfaces slide over eachother
Rolling friction occurs when a object rolls over a surface.
Fluid friction when an object moves through a fluid. EXAMPLE-air, water, oil, liquid, gas (ALL FLUIDS)
Lubricants (in friction) change sliding friction to fluid friction
What are the Three Laws of Motion? rest, constant motion, and accelerated motion
The Three Laws of Motion was developed by... Isacc Newton
First Law of Motion states: an object at rest will remain at rest and an object in motion will remain in motion at constant velocity unless an unbalanced force acts upon it.
First Law of Motion explains: motion when a balanced force acts on an object
Second Law of Motion explains: an unbalanced force acceleratesan object in the direction of that force. (THE LARGER THE FORCE IS, THE GREATER THE ACCELERATION WILL BE)
Second Law of Motion is written... force= mass x acceleration f= m x a or re-written for WEIGHT w = m x g
One Newton equals the force required to accelerate one kilogram of mass at one meter/second/second OR1 N = 1 kg x 1 m/sec/sec
Third Law of Motion states: for every action there is an equal and opposite reaction (EVERY FORCE MUST HAVE AN EQUAL AND OPPOSTIE FORCE)
Free fall (definition) the acceleration of a falling object is due to the force of gravity between the object and the earth.
Free fall (concept) all objects accelerate at the same rate regardless of their masses.
Projectile when any object is thrown in the air.
Gravity the attractive force between all objects in the universe
Newton's Law of Universal Gravitation all objects in the universe attract eachother by the force of gravity.
Obital motion object that orbits around another object
Unit of weight is in... Newton
Unit of mass is in... Kilogram
