Newton's Three Law's
An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
This law is often called
"the law of inertia".
An object that stays still will remain staying steal with unbalanced force.And an object that is in motion with there same speed and the same direction unless upon unbalanced force.
You can demonstrate when a car has stopped and stays there unless unbalanced force acts on it and it starts moving.
the win mill will stay at rest unless the wind blows and it will start moving.
Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).
Acceleration is made when force acts with mass.
By taking a ball and it does not have that much mass and pushing it and it will go faster or taking a heavy ball and pushing it will not go as fast.
the cars are moving fast in the picture looks like it is just lines moving by
For every action there is an equal and opposite re-action
For every action there is another reaction.
By taking something and it is going slow and then it goes faster when someone push it.
the picture shows the arrows go different directions.
