Force and Motion

Throughout this segment in Science I learned about inertia, what affects acceleration, and about action and reactions. Overall I learned all about Newton's three laws of motion.

Newton's 2nd Law

Newton's second law is acceleration of an object depends on both the mass of the object and the force applied.
The equation is F= ma. This is force equals mass times acceleration.
If you use more force on an object the acceleration will be greater.
If mass increases but force stays the same the acceleration will decrease.

Newton's three laws of motion

The law of inertia, the law of acceleration, and the law of action and reaction.
The first law states an object in motion will stay in motion and an object at rest will stay at rest until an unbalanced force acts on it. The second law states acceleration of an object depends on both the mass of the object and the force applied. Newton's third law states for every action there is an equal and opposite reaction.
Inertia is the tendency for an object to resist a change in motion.
If the mass is greater the inertia is greater, if the mass is less the inertia is less.
An example of all three laws is if a person was pushing a cart and it was full of groceries, so when it stops moving it is hard for you to start moving it again (1st law), it is harder to push because it has a greater mass than when it was empty (2nd law), and when the you push the cart the cart pushes back (3rd law).
