Newtons 2nd law of motion
The equation of this law is: F= ma
Anertia
An object's tendency to resist change.
The more mass an object has the more inertia that object has.For example a bus has more inertia then a bicycle since it has more mass then the bicycle. Inertia is also related to all forces of motion since no matter what law is applied in every one of them an object wants to resist the movement happening to it.
The speed of an object depend of the mass of the object and the amount of force applied to it. For example if the force applied to it was greater than the mass of the object the speed would be faster but if the mass of the object increased and the force applied on the object stayed the same the object would move slower.
newtons 1st law
On object will remain at rest or motion unless acted on by an external force.
newtons 3rd law
Every action has an equal opposite reaction.
