Force & Motion

Newton's 2nd law is 'The acceleration depends on the mass of the object and force applied'. This means that the mass and force applied affects the acceleration, any change to either aspect will completely change the acceleration.  The equation for this law is 'A=F/M'.

The equation of this law is 'A=F/M'. The A stands for acceleration. The F stands for force. M stands for mass. Each of these letters work together to make motion.

If you use more force on an object, the acceleration increases. Remember, any change to the force or mass changes the acceleration. Putting more effort into a force changes it.

If the mass increases with the force staying the same, the object slows down.  If there's more force, the object gets harder to push. The only way to make the acceleration faster is to use more force.

Newton's 3 laws of motion are Action Reaction, Law of Inertia, and Law of Force and Acelleration. Action Reaction is another name for the 3rd law. Law of Inertia is the 1st law. Finally, the Law of Force and Acelleration is the 2nd law.

Newton's 1st law states that an object in motion stays in motion, while an object at rest stays at rest unless it makes contact with an unbalanced force. Newton's 2nd law states that the force applied equals the acceleration times the object's mass. Newton's 3rd law states that for every action, there is an equal or opposite reaction.

Inertia is the tendency of an object to resist force. The amount of inertia an object has depends on its weight.  So if you push a anvil, it will take a lot of Force due to inertia.

The more mass an object has, the more inertia it has. It's like pushing a elephant! Due to the mass, it will resist force, which is the result of it's mass.

An example of the 1st law is when someone is sitting down. They don't move at all, unless an unbalanced force makes contact. An example of the 2nd law is pushing a kid compared to an adult. The mass is doubled, resulting in less acelleration. An example of the 3rd law is bouncing a basketball. Your hand forces the basketball down, and the basketball bounces back up, which is an opposite reaction.
