Newton's Laws of Motion

Newton's Laws of Motion

By Contrice Dodson

newton's First Law of Motion

Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.​

I DO- Give TWO examples of Newton's First Law of Motion.

Poll

1st Check- Newton's First Law of Motion states:

• 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 balanced force.

• An object that is not at stays at rest and an object that is not in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

• 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.

• 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 or balanced force.

Newton's Second Laws of Motion

Acceleration (gaining speed) happens when a force acts on a mass (object). Riding your bicycle is a good example of this law of motion at work. Your bicycle is the mass. Your leg muscles pushing pushing on the pedals of your bicycle is the force. When you push on the pedals, your bicycle accelerates. You are increasing the speed of the bicycle by applying force to the pedals

Some text here about the topic of discussion

Newton's Second Law of Motion​

Newton's Second Law also says that the greater the mass of the object being accelerated, the greater the amount of force needed to accelerate the object. Say you have two identical bicycles that each have a basket. One bicycle has an empty basket. One bicycle has a basket full of bricks. If you try to ride each bicycle and you push on the pedals with the exact same strength, you will be able to accelerate the bike with the empty basket MORE than the bike with the basket full of bricks. The bricks add mass to the second bicycle. With bricks in the basket, you would have to apply more force to the pedals to make the bicycle with bricks in the basket move.

Newton's Third Law of Motion

For every action, there is an equal and opposite reaction.​

​

Newton's third law states that for every action (force) in nature there is an equal and opposite reaction. If object A exerts a force on object B, object B also exerts an equal and opposite force on object A. In other words, forces result from interactions.
