Newtons laws
second law
The greater mass of the object the greater the amount of force needed to accelerate it.F=ma.The bigger an object is the harder it is to push
first law
An object will remain stationary or moving at a constant speed if their is no net force or resultant force acting on it,E.g if you roll a pen on earth it will stop because there are opposing forces like gravity and air resistance acting against it. But if you rolled a pen in space it would keep going because there are no forces acting against it.
third law
For every action there is an equal and opposite reaction of the same type. If you drop a pen, gravity will push it down but there must be an equal force from the table.
-
balanced and unbalanced
when one of the forces are bigger and change shape,speed or direction.
-
-
friction
The force between two objects.Friction causes an object to decelerate by acting in the opposite direction to the movement of the object.
