Welcome to Physics!
What I already know about physics
What I already know is that Newton had three laws called the law of inertia, the law of acceleration, and the law of action-reaction. What I also know is that more than one force acts upon an object these forces are called balanced and unbalanced forces. these forces can cause an object to change direction or to change in acceleration if they are acted upon an object. Some other things that I know about physics is that you can measure how fast something moves for example the distance measured in an allotted amount of time is called speed and a distance measured in an allotted amount of time with an given direction is called velocity,there's also one more its called acceleration its the change in speed or velocity.

Newton's Law
1. Law of inertia-an object that is motion will stay in motion will stay in motion and an object that is at rest will stay at rest until an unbalanced force is acted upon the object.
2. Law of acceleration- the greater the mass an object has the greater the force will be needed to accelerate the object and the least amount of mass an object has the least amount of force the object needs to be moved or accelerated.
3. Law of Action-Reaction- with every action there is an equal and opposite reaction.

Speed-distance measures in an allotted amount of time
Velocity- speed in a given direction
Acceleration- the change in speed or velocity
Velocity- speed in a given direction
Acceleration- the change in speed or velocity

What I had questions about
What I had questions about is why did newton decide to make these three laws and how did people find out about his laws? |
