ok look below for the explanation.

the first 1. gif is the rule #1 that an objects motion wont change unless another force pushes it. this means if something moves it wont stop moving until it is moved or stopped by another force. makes scence? ok let me explain further. so im on my hoverboard (they are awesome) and i start spinning. to stop pinning i can use my arms and/or legs to push it the other way to make it stop.

#2 heavier objects need more push/ force to move than a light objects. this means say you have a 10 year old and a ten year old. so the 10 year old throws the ten pound ball and the other 10 year old throws the 5 pound ball. of course, the five 5 pound ball will go farther because its lighter.

#3 for every action theres an equal and opposite reaction. that means both sides of an object using force. pleh so lets say as i used a bottle rocket (im so bad at drawing you probably thought i was sending a giraffe in a rocket) the bottom and the top of the object was using force and that was what made the object shoot up and spray the garbage stickman
