## INERTIA

States that every object in a state of rest or uniform motion remains in that state unless an external force is applied to it. Which means if an object is at rest (unmoving) it will stay like that unless some force moves it. Same with when its moving it'll move until something stops it whether it's static friction, sliding friction, or someone picking it of the ground.

## F= MA (F=10 M=5 A=2) (10=5x2)

Newton's second law of motion describes the relationship between an object's mass and the amount of force needed to accelerate it. Newton's second law is often stated as F=ma, which means the force (F) acting on an object is equal to the mass (m) of an object times its acceleration (a). This means the more mass an object has, the more force you need to accelerate it. And the greater the force, the greater the object's acceleration.

## ACTION REACTION

A force is a push or a pull upon an object that results from its interaction with another object. Some forces result from contact interactions (normal, frictional, tensional, and applied forces are examples of contact forces) . According to Newton, whenever objects A and B interact with each other, they exert forces upon each other. When you sit in your chair, your body exerts a downward force on the chair and the chair exerts an upward force on your body. There are two forces resulting from this interaction - a force on the chair and a force on your body. These two forces are called action andreaction forces and are the subject of Newton's third law of motion.

## REFLECTION

My partner and I went threw five cars and none of them worked. It always had something to do with the wheels and or the axles We got pretty close one time but then the wheel fell off. We think that are wheels were to Heavy even though the were just 2 CDs on one side of each axle So since ares never moved I think that was because of inertia. I also learnt how much Newtons 3 laws were used more than once everyday.
