A book stays still until moved. Which law explains this?
Inertia
What force opposes motion?
Friction
I happen when a person or object gives a push or a pull directly to another object to make it move. What type of force am I?
Applied force
A wider base makes an object more stable.. T or F

This type of force is associated with the attraction of iron nails
Magnetism
I determine whether an object resists toppling or collapses with ease.
Stability
The tendency to resist change in motion
