Day 5 - Interaction of Contact Force Flashcards
A body at rest will remain at rest and a body in motion will remain in motion unless it is acted upon by an external force
1st law of motion
It is the massive bodies that resist changes in their state of motion
Inertia
This law has the force acting on an object is equal to the mass of that object times its acceleration.
2nd law of motion
F=ma
2nd law of motion
For every action, there is an equal and opposite reaction forces occurs in pairs
3rd law of motion
It is the push or pull of an object. Objects must be in contact with each other to exert this. It never acts alone.
Force
This is a force that is applied when objects touch each other
Contact Forces
This force is applied when the objects aren’t touching each other
Non-Contact
It shows the chosen body by itself, free of its surrounding with vectors drawn to show to the magnitude and direction
