Newtons Laws of Motion
and other science stuff
First law
An object in motion tends to stay in motion unless an unbalanced force is applied to it, or an object at rest tends to stay at rest unless an unbalanced force is applied to it. (aka inerita)
the cart will keep moving till it hits the brick
Second Law
Aceleration depends on the objects mass and the amount if net force applies to it. or A=F/m
Third Law
For every action force there is an equal and opposite reaction force
Momentum
Momentum is something putting a force on an object and making that other object move for example newtons cradle you drop the first ball and the last ball moves when the first ball drops
Weightlessness
Weightlessness is the feeling of no weight. For example an astronaut in space
Mass
Mass is the amount of matter in an object
Newtons Law of Universal Gravitation
states that all things in space have a gravitational pull
