Newtons Laws of Motion By Bryce Tua

1st Law: "The Law of Inertia"

An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

The cars would keep going until they collide.

This car would keep going until it hits the brick wall.

The wall stays in motion until the-

-bot pushes it and his force acts upon the block.

Second Law: 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.

For an object with a constant mass m, the second law states that the force F is the product of an object's mass and its acceleration a:

Third Law: For every action, there is an equal and opposite reaction.

The action of the rocket in the video is the-

-propulsion system that pushes down on the ground.

The reaction allows the rocket to push upward with an equal force.

The third law of motion is like a cause and effect kind of theory.

In 1686 these three laws were presented by Sir Issac Newton
