When an object is at rest it will stay at rest unless an unbalanced fore acts upon it, same with motion

Matter that stays in rest or in unchanging motion unless acted upon by an external force

The state in which all forces are exactly in balance so there is no movement

The force felt between to surfaces when one attempts to slide against the other

The push or pull on an object with mass causes it to change its velocity

A force that is applied by objects in contact with eachother

A force that is applied without physical contact

Force=mass x acceleration (F=ma)

-9.31 m/s²

Every action has an equal opposite reaction

Mass x Velocity

Force x Time

The impulse applied to an object will be equal to the change in its momentum

All non zero numbers are significant

Zeros between two non zero digits are significant

Trailing zeros to the right of the decimal are significant

Leading zeros are not significant
