Newton's law and simple machines
You will learn something new
Newton's first law of motion
Newton's first law of motion - sometimes referred to as the law of inertia. first law motion says that unless a net force acts on an abject, the object will remain in constant speed will continue to move in a straight line and at a constant speed.

Newton's second law of motion
Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
- Newton's second law motion discribes how acceleration, mass, and net force are related. Acceleration is the rate at which the velocity of an object changes over time.
Newton's second law of motion
The person is pushing the car and the car is moving the person is using force into the car.
Newton's third law of motion
Explains how Newton's law motion works and also how you could use Newton's law motion.
Newton's first law of motion
Objects in motion will remain in motion and objects at rest will stay at rest unless acted upon by an outside force.

Newton's third law of motion
Newton's third law motion states that when one object exerts a force on a second object, the second exerts a force on the first object.
- This law is exemplified by what happens if we step off a boat onto the bank of a lake: as we move in the direction of the shore, the boat tends to move in the opposite direction (leaving us facedown in the water, if we aren't careful!).
This is 1,2,3 law of motion
First law:When viewed in an inertial reference frame, an object either remains at rest or continues to move at a constant velocity, unless acted upon by an external force.
Second law:The vector sum of the forces F on an object is equal to the mass m of that object multiplied by the acceleration vector a of the object: F = ma.

Newton's laws of motion song
Watch this video and here the song of Newton's laws of motion. You will learn a lot about Newton's laws
introduction
Simple machines are very cool because you can use them a lot for building. Newton's law of motion is very intesting because You learn about motion. Have you ever heard of seen or even use simple machines? Have you ever seen or heard of Newton's law of motion? If you haven't well here it goes you will learn so much from my flyer.
