newton's law of motion
Kuvakäsikirjoitus Teksti
- Newton's First Law of Motion- The Law of Inertia: An object at rest remains at rest and an object in motion remains in motion at a constant speed and in a straight line unless acted upon by an unbalanced force.Example: A book is on a table. The book is still at rest and will remain so until something (such as a human or a gust of wind) applies a force to it that causes it to move. rolling.
- Newton's Second Law of Motion- The Law of Force: The acceleration of an object depends on the mass of the object and the amount of force applied.Example: You're moving a couch over a floor. The quicker the couch moves, the harder you push. This is because the force you provide to the couch (the push) is precisely proportional to the box's acceleration.
- Newton's Third Law of Motion- The Law of Action/Reaction: Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first.Explanation: A box is pushed across the floor by someone. The box encounters a force in the opposite direction as the user pushes it, pushing back against the person's hands.
