Forces that accelerate!!

Forces are fun!! When an outside, unbalanced force acts upon an object, the object accelerates. (When balanced forces act upon an object like rubbing your temples, the force stays at rest.) The inertia of an object causes it to continue until it is acted upon by another force.

This week we focused on forces that accelerate, which relates to Newton's second law: the acceleration of an object is directly proportional to the net force on an object; the acceleration of an object is inversely proportional to the objects mass. This means that when the force increases, the object's will acceleration will increase. As the mass increases, the acceleration will decrease, and as the mass decreases, acceleration is greater.

Let's take a look at an example!! After eating a tasty lunch with my sister, I got thirsty so she rolled me one of the drinks she bought. Knowing acceleration and the mass of the can we can find the force that my sister used to get it to me.

To find this, we would first make a free body diagram and then solve it using the only formula we know.... Fnet=ma!!

Yay forces!
